im stuck, please help

(1 point) Let h(x) = f(x) . g(x), and k(x) = f(x)/g(x). Use the figures below to find the exact values of the indicated derivatives. 3 110 1/0 -3 3 3 1.0 -3 E- f(x) g(x) A. h'(-1) = 2 B. k'(1) = 4/3 (Enter dne for any answer where the derivative does not exist.)\f(1 point) Find the equation of the tangent line to the curve 2 sin x + 2 cos x at the point (0, 1/2). The equation of this tangent line can be written in the form y = mx + b where m= 1/(2 sin ( x ) + 2 cos ( x) and b = 1/2 Note: You can earn partial credit on this problem.
