I need help. I don't understand how to solve the problems.

g(2) f ( I) -1 h(x) -2 In T 3x - (k(x)) = f(x) - 2 fork(x) 20 h' (x) Problem 5 requires knowledge of Topic 3.6 5. Let - = g(f(x)). Find a y 6. Find k'(4). dxz atx = 5. Procedure/Method: Procedure/Method: Work/Solution: Work/Solution: g(x) 7. Let c(x) = h(x) Find c'(9). 8. Let d(x) =+ 3h(x). Find d' (4).
