Explain why the function is discontinuous at the given number a. (Select all that apply.) 2x2 - 9x - 5 f ( x ) = if x # 5 X - 5 a = 5 10 if x = 5 O lim f(x) and lim f(x) are finite, but are not equal. x - 5+ x-5 ( lim f(x) does not exist. x - 5 Of(5) and lim f(x) are finite, but are not equal. Of(5) is undefined. none of the above Sketch the graph of the function. J 12/ 12 / 12/ 12 10 10 10/ O 10 O 8 8 8/ 6 6 6- 4 4 4 2 2 X 2 4 6 8 10 X 12 2 4 6 8 10 X 12 2 4 6 8 10 X 12 2 6 8 10 12 (i)
