Question

Which point represent the location of the vertex of the

given function? *
f(x) = -2(x – 4)2 – 7?

Answer 1

The vertex point is (4, -7)

Explanation:

Compare withe the general form of the vertex form:

f(x) = a(x - h)^2 + k where (h, k) is the vertex.

f(x) = -2(x - 4)^2 - 7.

- so the vertex is (4, -7).

Answer 2

(4,-7) is the vertex

Explanation:

The equation of the parabola is of the form

y= a(x-h)^2 +k

where (h,k) is the vertex

f(x) = -2(x – 4)^2 – 7

(4,-7) is the vertex
