discontinuities because they disappear if we define or redefine f at a so that . The function in graph (c) has a jump discontinuity because left and right limits exist at a but are unequal. The discontinuity in graph (d) is an infinite discontinuity because the function has a vertical asymptote at a.

Is the discontinuity at a in graph (d) removable? Explain.
