Question

my answer and option different

Answer 1

If you were so kind to show us your answer, work, and the options we will give you better help :)

Answer 2

f(g(x)) = 3(x^(3)+5)-2 = 3x^(3)+13

f(g(x))^-1 = ((x-13)/3)^(1/3)

If x = -11 then ((-11-13)/3)^(1/3) = -8^(1/3) = -2

Answer 3

You have to pass the function G(x) as the parameter of f(x) so therefore, foreach x in the f(x) expression you calculate G(x)...
