Find inverse functions. Solve an equation of the form 𝑦 = 𝑓(𝑥) for a simple function f that has an inverse and write an expression for the inverse. Verify by composition that one function is the inverse of another. Read values of an inverse function from a graph or a table, given that the function has an inverse. Produce an invertible function from a non-invertible function by restricting the domain.
Students will be able to find the inverse of functions and use composition of functions to prove that two functions are inverses.
