In this problem, given the focus at (2,4) and directrix at y = 8. then it is implied that the parabola is facing downwards. The vertex hence is at the middle of the focus and the directrix, hence at (2, 6). The general formula of the parabola is y-k = -4a ( x-h)^2. Substituting, y -6 = -1/8 *(x-2)^2. Answer is A.

To find the value of x, we can actually simplify this thing down using the property that ln(e) = 1. You can think of it as "What power do I need to raise e to, to get e^5?" Let's do that:

So,
x = 5
