What is the discontinuity of the function f (x) = the quantity of x squared minus 3 x minus 28, all over x plus 4?

Hello there.

What is the discontinuity of the function f (x) = the quantity of x squared minus 3 x minus 28, all over x plus 4?

(-4,-11)

For the answer to the question above,

You get discontinuity when in this function you divide by 0. You will divide by 0 if x+4 = 0. That means that x = - 4

y value for this example doesn't matter because for x = - 4 you will have the discontinuity. Since the only answer that has - 4 as x value is D, that has to be the solution.

So the answer is (-4,-11)
