5. If ry + e" = e, find the value of y" at the point where r = 0. 6. A table of the functions f(x) and f'(x) and a graph of the piecewise linear function g(r) are shown below. I f (I) f'(I) -1 11 -7 2 -2 -2 5 2 9 3 3 0 4 4 1 2 5 2 2 3 y = g(I) (a) Given h(1) = f(g(r)), find h'(0). (b) Given p(I) = (g(1))" , find p'(2). (c) Given k(z) = g(f(z))2/3, find k'(1)
