Question

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

f(x) = 3x2 + 13
f(x) = 3x2 − 12x + 13
f(x) = 3x2 + 12x − 11
f(x) = 9x2 − 36x + 37

Answer 1

@Nnesha

Answer 2

(x-2)^2
use
(a-b)^2=a^2+b^2-2ab

Answer 3

in this case (x^2 +4-4x)

Answer 4

so it becomes 3(x^2 +4-4x)+1

Answer 5

just multiply now

Answer 6

it becomes....
Are you following me @boots_2000 ????

Answer 7

yeah

Answer 8

is the answer d?

Answer 9

Nopes its not D

Answer 10

3(x^2 +4-4x)+1
=3x^2+12-12x+1
=3x^2-12x+13

Answer 11

okay so its b right?

Answer 12

yes, but did you understand the steps?

Answer 13

yes
