14 Standards N-RN.1, 2: 1. Explain how the definition of the meaning of rational exponents follow from extending the properties of integer exponents to those values, allowing for a notation for radicals in terms of rational exponents. For example, we define 5 1/3 to be the cube root of 5 because we want (5 1/3 ) 3 to hold, so (5 1/3 ) 3 must equal 5 2. Rewrite expressions involving radicals and rational exponents using the properties of exponents A-SSE.1a,b, 3c: 1. Interpret expressions that represent a quantity in terms of its context a. Interpret parts of an expression, such as terms, factors, and coefficients b. Interpret complicated expressions by viewing one or more of their parts as a single entity. For example, interpret P(1+r)n as the product of P and a factor not depending on P 3. Choose and produce an equivalent form of an expression to reveal and explain properties of the quantity represented by the expression c. Use properties of exponents to transform expressions for exponential functions. For example, the expression 1.15 t can be rewritten as (1.15 1/12 ) 12t to reveal he approximate equivalent monthly interest rate if the annual rate is 15% A-CED.1-3: 1. Create equations and inequalities in one variable and use them to solve problems. Include equations arising from linear and quadratic functions, and simple rational and exponential functions 2.

15 3. Represent constraints by equations or inequalities, and by systems of equations and/or inequalities, and interpret solutions as viable or nonviable options in modeling context. For example, represent inequalities describing nutritional and cost constraints on combinations of different foods A-REI.10: 10. Understand that the graph of an equation in two variables is the set of all its solutions plotted in the coordinate plane, often forming a curve (which could be a line) F-IF.1, 2, 4-7e, 8b: 1. Understand that a function from one set (called the domain) to another set (called the range) assigns to each element of the domain exactly one element of the range. If f is a function and x is an element of its domain, then f(x) denotes the output of f corresponding to the input x. The graph of f is the graph of the equation y = f(x) 2. Use function notation, evaluate functions for inputs in their domains, and interpret statements that use function notation in terms of a context 4. For a function that models a relationship between two quantities, interpret key features of graphs and tables in terms of the quantities, and sketch graphs showing key features given a verbal description of the relationship. Key features include: intercepts; intervals where the function is increasing, decreasing, positive, or negative; relative maximums and minimums; symmetries; end behavior; and periodicit 5. Relate the domain of a function to its graph and, where applicable, to the quantitative relationship it describes. For example, if the function h(n) gives the number of person-hours it takes to assemble n engines in a factory, then the positive integers would be an appropriate domain for the functions 6. Calculate and interpret the average rate of change of a function (presented symbolically or as a table) over a specified interval. Estimate the rate of change from a graph Write and solve exponential growth and decay problems from a set of points Construct exponential functions given a graph or two input-output pairs CCSS: A-SSE.3c; A-CED.1-3; F-LE.2; F-IF.1,2 MACLE: AR.3.A Use and solve exponential growth and decay equations and inequalities to model real-life situations Construct exponential functions given a description of a relationship Interpret the parameters of an exponential function in terms of context CCSS: F-BF.1b; F.LE.2,5; A-CED.1,3 MACLE: AR.4.A 15
16 7. Graph functions expressed symbolically and show key features of the graph, by hand in simple cases and using technology for more complicated cases e. Graph exponential and logarithmic functions, showing intercepts and end behavior, and trigonometric functions, showing period, midline, and amplitude 8. Write a function defined by an expression in different but equivalent forms to reveal and explain different properties of the function b. Use properties of exponents to interpret expressions for exponential functions. For example, identify percent of rate of change in functions such as y = (1.02) t, y = (0.97) t, y = (1.01) 12t, y = (1.2) t/10, and classify them as representing exponential growth or decay F-BF.1b, 3: 1. Write a function that describes a relationship between two quantities b. Combine standard function types using arithmetic operations. For example, build a function that models the temperature of a cooling body by adding a constant function to a decaying exponential, and relate these functions to the model 3. Identify the effect of the graph of replacing f(x) by f(x) + k, k f(x), and f(x + k) for specific values of k (both positive and negative); find the value of k given the graphs. Experiment with cases and illustrate and explanation of the effects on the graph using technology. Include recognizing even and odd functions from their graphs and algebraic expressions for them 16

For example, given a graph of one quadratic function and an algebraic expression for another, say which has the larger maximum F-BF.3 3. Identify the effect on the graph of replacing f(x) by f(x) + k, k f(x), f(kx), and f(x + k) for specific values of k (both positive and negative); find the value of k given the graphs.

For example, a question may be asked: When you place rice on the chess board: 1 grain on the first square, 2 grains on the second square, 4 grains on the third, and so on doubling the grains of rice on each square... 27
28 Assessments/Evaluations The students will be assessed on the concepts taught using a variety of modalities: Direct teacher observations Projects with scoring guides A Reality Series Project: Students will work with a partner to research a real-world application of arithmetic and geometric sequences and series At the conclusion of their research, they will make a poster presentation of their findings and present it to the class Quizzes Homework assignments see pacing guide Formal Common Assessment Unit G test Mastery Level: 80% Instructional Resources/Tools Textbook(s): (sample copies on bookshelf) Pearson Algebra 2 Common Core (primary source) Holt Algebra 2 Common Core Edition Houghton Mifflin On Core Mathematics: Algebra 2 Website(s): Graphing calculator Computer simulation software Sequence and series apps 28
