a) Determine for which values ofx=athelimxaf(x) exists butfis not continuous atx=a.

b) Determine for which values ofx=athe function is continuous but not differentiable atx=a.

Consider the graph. (Enter your answers as comma-separated lists. If an answer does not exist, enter DNE.) y (a) Determine for which values ofx = a the lim f(X) exists but fis not continuous at x = a. x>a (b) Determine for which values of x = a the function is continuous but not differentiable at x = a
