2. 3 1. Find the exact location of all absolute extrema of the function f(x)=x- 12x with domain [-7, 7]. The graph of the derivative of a function f is shown. Determine the x-coordinates of all stationary and singular points off. (Assume that f(x) is defined and continuous everywhere in [-10, 10].)
