Hi! So for this question I was wondering how you would find the derivative of the function based on the graph. Would you have to calculate the original function, derive it then plug in 1 and 8? Can you please go through each step below.

Let F03) = f(9($))- (a) Find F'(l) and F'(8). (1)) Use linear approximation to estimate F(0.9). (c) There are three values of a: in (0,10) at which F is not differentiable. Find them; explain your reasoning
