The standard form of the equation of a parabola is y= 1/2 x^2 - 4x + 21 what is the vertex form of the equation?

a box 3 3/4 feet long or 4+ feet.

step-by-step explanation:

40% off the regular price is the correct answer.

step-by-step explanation:

g = (2, 2)

step-by-step explanation:

given the ratio is 1 : 1 then f is the midpoint of eg

let the coordinates of g = (x, y)

using the midpoint formula

(0 + x) = 1 ( multiply both sides by 2 )

0 + x = 2 ⇒ x = 2

similarly

(4 + y) = 3 ( multiply both sides by 2 )

4 + y = 6 ( subtract 4 from both sides )

y = 2

coordinates of g = (2, 2)

i think it is 70
