Answer:
Explanation:
To find the indicated values:
f(9) = 1 (Find the value of f(x) when x = 9.)
If f(x) = 9, then x = 8 (Find the value of x when f(x) = 9.)
f^{-1}(3) = 6 (Find the value of f^{-1}(x) when x = 3.)
If f^{-1}(x) = 7, then x = 3 (Find the value of x when f^{-1}(x) = 7.)
So, the answers are:
f(9) = 1
If f(x) = 9, then x = 8
f^{-1}(3) = 6
If f^{-1}(x) = 7, then x = 3
