Find the limit L (if it exists). If it does not exist, explain why. (If an answer does not exist, enter DNE.) lim 2 - 49 The limit does not exist at x - 7 because the function does not approach R7) as x approaches 7. O The limit does not exist at x - 7 because the function is not continuous at any x value. O The limit does not exist at x - 7 because the function value is undefined 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. Submil Answer 7 DETAILS LARCALC11 2.R.013.
