Help with number 3 please

3. Let
x;
(0 < x < 1)
f(x) = {
(1<x < 2)
2x;
i) Is the function f(x) continuous on [0, 2]? Explain (a graph is not a proof!)
ii) Compute AND graph the function
F(x) = | f(t)dt
Hint: Imitate the proof of the problem in the notes/video about the relatioship between
integration and differentiation.
ii) Is the function F(x) continuous at x =
1?
iii) Does F'(1) exist? Explain. (Hint: Compute the derivative of F(x) from the left and
right at x =
iv) Does iii) violate the FTC II that states F'(x) = f(x) for all x at which f is continuous?
