8. The graph of function f (x) is shown below: (10 marks) a) For what value(s) of x is f(x) undefined? (1 mark) f ( xx ) is undefined at > = 5 b) What type of discontinuity exists at x = -2? (1 mark) Jump discontinuity c) At what value(s) of x is the function non-differentiable? (3 marks) The function is non - differentiable at x = 3. d) Evaluate each limit: i) lim f(x) = =2 x--2 ii) lim f (x) = 1 x- -2+ iii) lim f(x) iv) lim f (x) = 0 X- 3 v) lim f(x) x-5
