4. Given the following graph of function f, please answer the following: -5 0 5. 0 -5- (a) (1 point) Find lim-3- f(x). (b) (1 point) Find f(-3). (c) (1 point) Find lim-2 f(x). LO 5 (d) (1 point) Is f'(4) positive, negative, or zero? (e) (1 point) Find f'(-2) exactly. (Please note that this segment of the function is linear.) (f) (1 point) Find all x-values at which f is not continuous. (g) (1 point) Find all x-values at which f is not differentiable.
