Question

Y = 2(x – 3)2 - 4
Convert to standard form

Answer 1

4x - y = 16

Explanation:

y = 2(x – 3)2 - 4

When written in standard form, this will be the answer --->

4x - y = 16

Answer 2

y = 2x² - 12x + 14

Explanation:

The equation of a parabola in standard form is

y = ax² + bx + c ( a ≠ 0 )

Given

y = 2(x - 3)² - 4 ← expand (x - 3)² using FOIL

= 2(x² - 6x + 9) - 4 ← distribute parenthesis

= 2x² - 12x + 18 - 4

y = 2x² - 12x + 14 ← in standard form
