Outcomes

A-CED.2

Create equations in two or more variables to represent relationships between quantities; graph equations on coordinate axes with labels and scales.

F-IF.8b

Write a function defined by an expression in different but equivalent forms to reveal and explain different properties of the function. b. Use the properties of exponents to interpret expressions for exponential functions. Apply to financial situations such as Identifying appreciation/depreciation rate for the value of a house or car some time after its initial purchase: V = P(1 + r)^n

F-BF.1a

Write linear, quadratic, and exponential functions that describe relationships between two quantities. a. Determine an explicit expression, a recursive process, or steps for calculation from a context.
