1) The function f(x) has the graph shown below. Using this graph, fill out the table below. a f(a) lim f (x) x-+a lim f (x) x-at x-a limf (x) Is f continuous at x = a ? |Is f differentiable at x = a ? 0 -2 2 2) Determine, algebraically, whether or not the following limit exists. If, so compute the limit. (a) lim Vx - 4 -= x-4 x3+2 (b) lim x+6 X --6 x2 - 36 (c) lim x- -5+ (x-5)3
