DETAILS SCALCET9M 2.5.024. MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER Explain why the function is discontinuous at the given number a. (Select all that apply.) if x #4 f(x) = 2x2 • 7x - 4 X-4 8 a = 4 if x = 4 lim f(x) does not exist. n f(4) and lim f(x) are finite, but are not equal. x4 O f(4) is undefined. lim f(x) and lim x 4f(x) are finite, but are not equal. none of the above Sketch the graph of the function.
