Question

The standard form of the equation of a parabola is x-y^2+10y+22.what is the vertex form of the equation?

A.x=(y+10)^2-78
B.x=(y+5)^2+12
C.x=(y+5)^2-3
D.x=(y+10)^2+2

Answer 1

x = y^2 + 10y + 22

Divide 10 by 2 to give 5 which becaoses the second term in the parentheses

x = (y + 5)^2 - 25 + 22

x = (y + 5)^2 - 3 Answer.
