Answer:

$(a)\ f^(-1)(-15) = -6$

$(b)\ f^(-1)(4) + f(9)=0$

Explanation:

Given

The attached table

$(a)\ f^(-1)(-15)$

This represents an inverse function.

So, we look into x row for its value.

i.e.

f^(-1)(-15) = -6

$(b)\ f^(-1)(4) + f(9)$

Just like (a)

f^(-1)(4) = -11 ---- by looking into the x rows

f(9) = 11

So:

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

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