Consider the following. f(x) = x - 1 ifx#1 1-1 if x = 1 X -2 2 -3 Use the graph to find the limit below (if it exists). (If an answer does not exist, enter DNE.) lim f(x) x- 1Consider the following limit. lim (9x + 4) x-4 Find the limit L. L = (a) Find the largest 6 > 0 such that (f(x) - L| 0 such that [f(x) - L| 0 such that (f(x) - L| 0 such that (f(x) - LI
