Use the graph to find the limit L (if it exists). If the limit does not exist, explain why. (If an answer does not exist, enter DNE.) g(x) = -2x X - 4 8 12 -8 (a) lim g(x) x - 49 The limit does not exist at x - 4 because the function does not approach f(4) as x approaches 4. The limit does not exist at x = 4 because the function increases and decreases without bound as x approaches 4. The limit does not exist at x - 4 because f(4) + 4. The limit does not exist at x = 4 because the function is not continuous at any x value. The limit exists at x = 4 ( b ) lim g(x) X -0- L = O The limit does not exist at x = 0 because the function does not approach f(0) as x approaches 0. O The limit does not exist at x - 0 because the function is not continuous at any x value. O The limit does not exist at x - 0 because the function increases and decreases without bound as x approaches 0. The limit does not exist at x - 0 because F(0) 0. O The limit exists at x = 0
