Question

What is the standard form of this function?

Rx) = (x - 2)2 + 6
A. f(x) = x2 - 8x + 10
B. Rx) = -X2 - 8x + 10
C. Rx)=-x2 - 6x + 10
D. Rx) = x2 - 4x + 10

Answer 1

D. Rx) = x2 - 4x + 10

Explanation:

R(x)=(x-2)^2+6

R(x)=(x-2)^2+6

=(x-2)(x-2)+6

=x^2-2x-2x+4+6

=x^2-4x+10

R(x) = x^2 - 4x + 10

Option D is the answer
