MEDAL AND FAN
Rewrite f(x) = –2(x − 3)^2 + 2 from vertex form to standard form

Answer 1

First define what vertex and standard form is:

vertex form : \(\sf y= a(x-h)^2+k\)

Standard form: \(\sf y=ax^2+bx+c\)

Answer 2

k and c are both constants.

Answer 3

-2x^2+12x+20

Answer 4

\[(x-3)^2 = x^2-6x+9 \]\[-2(x^2-6x+9) = -2x^2+12x+18+2\]\[-2x^2+12x+20 ~\checkmark\] Correct.
