Consider the function f(x) = x" -9 Which of the following is true about f(x)? x - 3 Of(x) has a removable discontinuity at x = 3 because f(3) is not defined. Of(x) has a jump discontinuity at x = 3 because lim f(x) does not exist. x-+3 Of(x) is continuous at x = 3 because lim f(x) exists. Of(x) has an infinite discontinuity at x = 3 due to a vertical asymptote
