Answer:
n(B) = 4
Step-by-step explanation:
There are four (4) elements in set B.
n(B) = 4

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.
