Answer 7

first find the f^-1(x) ..

Answer 8

we have y = x+ 9 to find f^-1(x)
first exchange x & y so we get x = y + 9 now solve this equation for y

so we will get y = x - 9 now replace y by f^-1(x) so f^-1(x)= x-9
now find f^-1(5)= 5 - 9 = -4
So to find (fof^-1)(5)= f(f^-1(5)) = f(-4) = -4 + 9 = 5
