Standard Find inverse functions. • 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) = 2x^3 or f(x) = (x+1)/(x–1) for x ? 1. • (+) 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.
