Question

Rewrite f(x) = 2(x − 1)2 + 3 from vertex form to standard form.

f(x) = 2x2 + 5
f(x) = 4x2 − 8x + 7
f(x) = 2x2 + 4x + 5
f(x) = 2x2 − 4x + 5

Answer 1

He knew what he was doing.

Answer 2

Explanation:

f(x) = 2(x − 1)² + 3

= 2 ( x² - 2x +1) +3

= 2x² - 4x +2 +3

f(x) = 2x² − 4x + 5 .....standard form.
