Q 1. (01.08 MC) f ( x ) = x2 - 9 Consider the function x -3 Which of the following is true about f(x)? (1 point) O lim f(x) f(x) is continuous at x = 3 because x-3 exists. Of(x) has a removable discontinuity at x = 3 because f(3) is not defined. lim f(x) f(x) has a jump discontinuity at x = 3 because x-+3 does not exist. Of(x) has an infinite discontinuity at x = 3 due to a vertical asymptote
