Explain why the function is discontinuous at the given number a. (Select all that apply.) f(x) = {2x2−9 x−5 x−5 if x ≠ 5 10 if x = 5 a = 5 limx→5+ f(x) and limx→5− f(x) are finite, but are not equal. f(5) and limx→5 f(x) are finite, but are not equal. limx→5 f(x) does not exist. f(5) is undefined. none of the above Sketch the graph of the function.
