Algebra II 7-7 quiz • Find the inverse of the function y = 4x-7. Is the inverse a function? • Find the inverse of y = √x +9. Is the inverse a function? • Graph the relation y = 2x2 – 2 and its inverse. • For the function f(x) = 2x2 – 1 and f -1, and the domain and range of f and f-1. Determine whether f-1 is a function. • If f(x) = 5x + 8, find (f-1o f)(59) and (f o f-1)(3001). • A right triangle has a leg of length x and a hypotenuse of length 2x. Write an equation to find the length s of the other leg, and use it to estimate s when the hypotenuse has a length of 5cm.
