Find the standard form of the equation of the parabola with a focus at (0, 2) and a directrix at y = -2.

a. y2 = 2x
b .y = one divided by twox2
c .y2 = 8x
d. y = one divided by eightx2

D. y = one divided by eightx2

Step-by-step explanation:

The standard form of the equation of the parabola with a focus at (0, 2) and a directrix at y = -2 is y = one divided by eightx2.

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

answer:

f(5/2) = 10/3

i hope this you!
