Question

sketch f(2) = 4 f ' (2) does not exist and f(-1) is an absolute maximum

Answer 1

there must be more info to this...

Answer 2

actually, this question is incomprehensible on a number of levels
please be sure to type your questions clearly

Answer 3

sketch the graph of a function f with the following properties

Answer 4

Hint: Since f(2) exists and f'(2) doesn't exist
draw your graph so that there is a sharp turn at x=2
Recall the graph of y=|x| is continuous at x=0 and not differentiable at x=0 because of the sharp turn at x=0

Answer 5

let me know if you need any clues about what happens at x=-1

Answer 6

If you want you can draw a graph that has the properties you mention and I will check it
