What is the vertex of g(x) = 3x2 − 12x + 7?
a) (−6, −5)
b) (−2, −5)
c) (2, −5)
d) (6, −5)

C)   (2, -5).

Step-by-step explanation:

Convert to vertex form:

3x^2 - 12x + 7

= 3(x^2 - 4x) + 7

Completing the square:

= 3[ (x - 2)^2 - 4)] + 7

= 3(x - 2)^2 - 12 + 7

= 3(x - 2)^2 - 5.

Comparing with the general form

a(x - b)^2 + c  we see that the vertex is (b, c)  =   (2, -5).

the awnser is c
