What is the equation of the parabola? coordinate plane with a parabola facing down with vertex at 0 comma 5, the point 0 comma 3 and a horizontal line going through 0 comma 7

y = −one eighthx2 + 5
y = one eighthx2 + 5
y = one eighthx2 − 5
y = −one eighthx2 − 5

Okay so i dont know the answer completly but I know what its not. Its not y=1/8x2- 5

So i think it might be y=-1/8x2-5

Step-by-step explanation:

x = 2

step-by-step explanation:

if sr parallel to ba then the sides bc and ac are in proportion, that is

= ← substitute values

= ( cross- multiply )

27x = 6(4x + 1)

27x = 24x + 6 ( subtract 24x from both sides )

3x = 6 ( divide both sides by 3 )

x = 2
