Question

What is f(x) = 2(x - 3)² + 4 when written in the form f(x) = ax² + bx + c?
a. f(x) = 2x² - 12x + 22
C. f(x) = 2x2 + 12x +22
b. f(x) = 2x2 - 12x + 10
d. f(x) = 2x2 - 12x – 10​

Answer 1

Hey buddy,

2(x - 3)² + 4

2(x² + 9 - 6x) + 4

2x² + 18 -12x + 4

2x² - 12x + 22

So option a is correct.

Hope it helps!
