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)

Answer:
y = 5x
Step-by-step explanation:
The equation for direct variation is y = kx, where k is the factor of variation. So we know that y and x must fit into this formula.
They've given us a y and x value to solve for k.
y = kx
15 = 3k
15/3 = k
<u>k = 5</u>
Plug k back into our equation.
y = 5x
