Hello,
Would anyone know how to approach this question?
Given that f:x → (ax+b)^3, x ∈ ℝ, and that when x = 2, f(x) = 1, and f'(x) = 6, find the values of a and b.
The answer at the back of my book says, a = 2 and b = -3.
I think I am supposed to use the chain rule. If so, how would I go about setting up the equation?
Thanks.
