Find the limit L (if it exists). If it does not exist, explain why. (If an answer does not exist, enter DNE.) 2 lim f(X) where f(x) = (X 7} I X 5 7 \"*7 7 X, X> 7 O The limit does not exist at x = 7 because the function is not continuous at any X value. 0 The limit does not exist at x = 7 because the function does not approach f(7) as X approaches 7. O The limit does not exist at x = 7 because the function value is undened at x = 7. O The limit does not exist at x = 7 because the function approaches different values from the left and right side of 7. O The limit exists at X = 7
