The vertex form of the equation of a parabola is y=2(x+4)^2-7. what is the standard form of the equation. a. y=2x^2+12x+12 b. x=2y^2+8y+12 c. y=4x^2+4x+8 d. y=2x^2+16x+25

Step-by-step explanation:

To obtain the standard form of the equation of the parabola y=2(x+4)^2-7, first perform the indicated operations:

y = 2[x^2 + 8x + 16 - 7], or

y = 2[x^2 + 8x + 9],

or y = 2x^2 + 16x + 18

None of the given possible answers match.  The fourth one, D, is closest to the above result, differing only in the constant term (25 versus 18).

step-by-step explanation:

step-by-step explanation:

we are given

since, we have to isolate x on anyone side

so, we can move all x terms on one side

subtract both sides by 2x

add both sides by 9

divide both sides by 4

we get
