A2) Find the derivative of the following functions: x2 + 2 (a). f(x) x2 2 - (b). f(x) = 2 tan-1(x) – 3" (c). f(x) : = (x + 2 sin x) (1 – 8 cos x) tanx (d). g(x) = 2 – secx -

Do not use technology. The figure below shows the graph of f', the derivative of f. The function f is a twice differentiable function on x E (-∞o, co), f'(-0.8) = 0, and f"(1.3) = 0. -3 (a) For what values of x is f increasing? (Enter your answer using interval notation.) (b) For what values of x is the graph of f concave downward? (Enter your answer using interval notation.)
