Question

The function g(x) = 3x2 − 12x + 7 written in vertex form is g(x) = 3(x − 2)2 − 5. What is the vertex of g(x)?

Answer 1

Answer: C. (2,-5) is correct.

Answer 2

The equation is given as:

g(x) = 3x2 − 12x + 7 and in vertex form:

g(x) = 3(x − 2)^2 − 5

The vertex form general equation is:

y = a(x + h)^2 − k

where h and k are the vertex coordinates.

Therefore, the vertex for this equation is:
(-2, 5)
