Suppose that f(x + h) - f(x) = 2hx + 7h - 6h2. Find: f'(ac) =Suppose that f(x + h) - f(x) = 5hx2 + 2hx - 3h2x + 1h2 + 3h3. Find: f' (z) =Use the given graph of the function to find the mvalues for which f is not differentiable. Answer (separate by commas): .1: : | Note: You can ciick on the graph to enlarge the image
