Ax)= (x - 2x -2, x# 3 4, x=3 x -3- x -+ Hint: Find lim f(x), lim f(x), and f(3). Then use the definition of a removable discontinuity to explain your conclusion. 8. Use the graph of f(x) below to answer each of the questions that follow - NW a. Identify those values of x for which f(x) has a removeable discontinuity b. Identify those values of x for which f(x) has a non-removeable discontinuity. Answers: 1. 5 4
