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 discontinuity. Since the only answer that has -4 as x value is D, that has to be solution.
Answer is D
Answer:
28
Step-by-step explanation:
