Question

The function m is given in three equivalent forms.​

Answer 1

B; (-4, -8)

Explanation:

The given forms of the equation are standard form, vertex form, and intercept form.

It is not surprising that the vertex form yields the vertex most quickly.

B) m(x) = 2(x +4)² -8

Compare this to the generic vertex form ...

f(x) = a(x -h)² +k . . . . . . . . . vertex (h, k)

We see that the vertex is (h, k) = (-4, -8).
