26. Let f (x) = 4x2 9 and g(x) = x 3.

(a) Find the composite function ( f o g)(x) and simplify. Show work.

(b) Find ( f o g)(2) . Show work.

28. Given the function

1

f(x)= 2+ __ x, find the formula for the inverse function. Show work.

8

I tried to type the equation as (1/8) or 1 over 8, hopefully its understandable.
