Hello,and please help me with these three questions:

PART B 6. For the function f(x) in the graph below, determine the following: a. lim f(x) b. lim f(x) c. lim f(x) d. f(2) x- -2+ x-2 x-2+ 2- . (2, 2) (-2, 0) /2 4 6 8 -2- (2, -1) K 7. Use the graph to find the limit, if it exists. a. lim f(x) b. lim f(x) c. lim f(x) *-2 x-2 x-+3 4 7 3- 2- 2 2 1- O- VX 0 1 2 W. 4 O 2 W - 4 0 2 W - 41 1. For each function, sketch the graph of the function. Determine the indicated limit if it exists. a. f(x) = x + 2, ifx 2'*-2 4x, if x 2 2 ; lim f(x) c. f(x) = -, if x
