Which of the following functions f has a removable discontinuity at a? If the discontinuity is removable, find a function g that agrees with f for x ≠ a and is continuous at a. (If an answer does not exist, enter DNE.) (c). f(x) = [[sin(x)]] , a = Recall that [[h(x)]] means the largest integer that is less than or equal to h(x).)
