1. f(x) = 1/4 (x - 1)^2 - 9. What is the image set of the function f? Express in interval notation.
g(x) = 1/4 (x - 1)^2 - 9. (1 ≤ x ≥ 7). Specify the domain and image set of the inverse function g^-1, and find it's rule.
I really don't understand what happens in these questions. I have looked at numerous examples, the easy ones look like it's similar to finding the range, and the hard ones i just don't get. Can someone please break it down for me.
