Answer:

f^-1 (-15) = -6

f^-1(4) + f(9) = 0

Explanation:

f^-1 (-15) =

Look where the output is -15 and find the x value ( x=-6)

Since where are using the inverse function, the input becomes the output and the output and the output becomes the input

f^-1 (-15) = -6

f^-1 (4) = -11 (inverse function)

f(9) = 11 ( regular function)

f^-1(4) + f(9) = -11+11 = 0
