Building Functions

Resources

Build a function that models a relationship between two quantities. [Quadratic and exponential]
1. Write a function that describes a relationship between two quantities. tools-icon
a. Determine an explicit expression, a recursive process, or steps for calculation from a context.
b. Combine standard function types using arithmetic operations.
Build new functions from existing functions. [Quadratic, absolute value]
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.

4. Find inverse functions. tools-icon
a. Solve an equation of the form f(x) = c for a simple function f that has an inverse and write an expression for the inverse.
For example, f(x) =2x3.
