MARK & VIRGE DAY 1-Derivatives AP DAILY LIVE REVIEW AB CALCULUS Functions f, g, and h are twice-differentiable functions with g(5) = h(5) = 1. The line y = 1 -(x - 5) is tangent to both the graph of g at x = 5 and the graph of h at x = 5. (a) Find g'(5). (b) Let b be the function given by b(x) = 2x2g(x). Write an expression for b'(x). Find b'(5). olds (c) Let w be the function given by w(x) = shed Write an expression for w'(x). Find w'(5). (d) Use the tangent line to the graph of h(x) at x = 5 to approximate h(4.8). e) Let p be the function given by p(x) = g(x) + f(3x). Given that p'(5) = , find f'(15)
