�A.SSE.3 Choose and produce an equivalent form of an expression to reveal and explain properties of the quantity represented by the expression.�C. Use the properties of exponents to transform expressions for exponential functions. For example 8^t can be written as 2^3t.
A.CED.1 Create equations and inequalities in one variable and use them to solve problems. Include equations and inequalities arising from linear, quadratic, simple rational, and exponential functions.�a. Focus on applying linear and simple exponential expressions.
A.CED.2 Create equations in two or more variables to represent relationships between quantities graph equations on coordinate axes with labels and scales.�a. Focus on applying linear and simple exponential expressions.
F.LE.1 Distinguish between situations that can be modeled with linear functions and with exponential functions.�c. Recognize situations in which a quantity grows or decays by a constant percent rate per unit interval relative to another.
F.LE.2 Construct linear and exponential functions, including arithmetic and geometric sequences, given a graph, a description of a relationship, or two input-output pairs (include reading these from a table).
F.LE.5 Interpret the parameters in a linear or exponential function in terms of a context.
F.BF.1 Write a function the describes a relationship between two quantities. a. Determine an explicit expression, a recursive process, or steps for calculation from context. i. Focus on linear and exponential functions.
F.IF.9 Compare properties of two functions each represented in a different way (algebraically, graphically, numerically in tables, or by verbal descriptions). For example, given a graph of one quadratic function and an algebraic expression for another, say which has the larger maximum.�b. Focus on linear, quadratic, and exponential functions.
