Targets & Standards
In Algebra 2, students analyze and apply operations using multiple representations of functions to compare, interpret data, and make inferences. Functions include (but not limited to) linear, exponential, quadratic, absolute value, inverse, piecewise, cubic, polynomial, trigonometric, logarithms, etc. They use statistics in real world contexts to develop solutions.
Essential Standards
Target D: Interpret the structure of expressions. (DOK 1,2)
Target L: Interpret functions that arise in applications in terms of the context. (DOK 1, 2)
Claim 3: Build New Functions & Rational Expression Operations (DOK 2, 3, 4)
Claim 4: Express & Evaluate Logarithms, Translate Between Logs in any Base &
Simplify Logarithmic Functions (DOK 2, 3, 4)
A-SSE.A.2 Use the structure of an expression to identify ways to rewrite it.
For example, see x^4 – y^4 as (x^2)^2 – (y^2)^2, thus recognizing it as a difference of squares that can be factored as (x^2 – y^2)(x^2 + y^2).
A-CED.A.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. Modeling Standard
There are no substandards for this standard.
A-CED.A.2 Create equations in two or more variables to represent relationships between quantities; graph equations on coordinate axes with labels and scales. Modeling Standard
There are no substandards for this standard.
F-IF.C.7 Graph functions expressed symbolically and show key features of the graph, by hand in simple cases and using technology for more complicated cases. Modeling Standard
b. Graph square root, cube root, and piecewise-defined functions, including step functions and absolute value functions.
F-IF.B.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. Modeling Standard
Key features include: intercepts; intervals where the function is increasing, decreasing, positive, or negative; relative maximums and minimums; symmetries; end behavior; and periodicity.
F-TF.A.2 [Embed F-TF.A.1 & F-TF.A.2.1] Explain how the unit circle in the coordinate plane enables the extension of trigonometric functions to all real numbers, interpreted as radian measures of angles traversed counterclockwise around the unit circle. Modeling Standard
There are no substandards for this standard.
Embed with F-TF.A.2, F-TF.A.1 Understand radian measure of an angle as the length of the arc on the unit circle subtended by the angle. Modeling Standard
There are no substandards for this standard.
Embed with F-TF.A.2, F-TF.A.2.1 Graph all 6 basic trigonometric functions. Modeling Standard
There are no substandards for this standard.
F-BF.3 Identify the effect on the graph of replacing f(x) by f(x) + k, kf(x), f(kx), 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 an explanation of the effects on the graph using technology.
Include recognizing even and odd functions from their graphs and algebraic expressions for them.

Supporting Standards
A-SSE.1 Interpret expressions that represent a quantity in terms of its context. Modeling Standard
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 as the product of and a factor not depending on .
F-BF.A.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.
F-LE.4.1 Prove simple laws of logarithms. CA Modeling Standard
There are no substandards for this standard.
A-SSE.4 Derive the formula for the sum of a finite geometric series (when the common ratio is not 1), and use the formula to solve problems. Modeling Standard
For example, calculate mortgage payments.
