Question

The vertex form of the equation of a parabola is x = (y - 3)2 + 41.

What is the standard form of the equation?.
O A. x = y2 + 6y+41
O B. x = y2-6y+ 50
O c. x= y2 +y+22
O D. x = 3y2 - 6y + 50

Answer 1

B

Explanation:

x = (y - 3)² + 41 ← expand factor using FOIL

x = y² - 6y + 9 + 41 ← collect like terms

x = y² - 6y + 50 → B
