<PRE><B>Question 1135884</B>
(f o g)(x) = 3(3x-1)^2 -(3x-1) -7 = 3(9x^2 -6x +1) -3x +1 -7 =
:
27x^2 -18x +3 -3x +1 -7 = 27x^2 -21x -3
:
(f ∘ g)(x) = 27x^2 -21x -3
:
I assume the problem does not want the inverse of the composite
:
Rather, just evaluate the composite at x = -1
:
(f o g)(-1) = 27(-1)^2 -21(-1) -3 =
:
27 +21 -3 = 45
:
