Hi I have some questions I hope they can be answered!

1) Assume that f(3) = 4 and f is invertible. Name a point that must be on the graph of y = f^{-1}(x). 2)

 

2) What is the range of f(x) = -\frac12\sqrt{-x^2 + 6x + 7}? 3) Let f(x) = 2x + 5 and g(x) = x^2 - x. What is g(f(x))?

1. (-1,2)

 

2. g(f(x)) = 13.
