Question

The vertex form of the equation of a parabola is y=4(x-2) squared minus one what is the standard form of the equation

Answer 1

Answer:

y = 4x² - 16x + 16

Step-by-step explanation:

Standard form is y = ax² + bx + c

To convert from vertex form to standard form multiply out the equation

1. Solve (x-2)² using F.O.I.L.

(x - 2) · (x - 2) = x² - 4x + 4

y = 4(x² - 4x + 4)

2. Distribute the 4

y = 4x² - 16x + 16
