Answer:
1
Step-by-step explanation:

The independent variable is the rate that water is flowing into the pool, and the dependent variable is the depth of water in the pool.
I believe this would be the case due to the fact that we are not in control of the flow yet the flow impacts the depth. So flow would be independent while the pool depth would be dependent on the rate of flow.

Let's solve ~
Equation of directrix is : y = 1, so we can say that it's a parabola of form : -

- h = x - coordinate of focus = -4
- k = y - coordinate of focus = 5
- a = half the perpendicular distance between directrix and focus = 1/2(5 - 1) = 1/2(4) = 2
and since the focus is above the directrix, it's a parabola with upward opening.
