Question

What is the vertex of the graph of the function f(x) = x2+8x-2?

Answer 1

Answer:

the answer is (-4,-18)

Answer 2

Answer:

The vertex is at (-4, -18).

Step-by-step explanation:

f(x) = x^2 + 8x - 2

Covert to vertex form:

f(x) = (x + 4)^2 - 16 - 2

f(x) = (x + 4)^2 - 18.

So the

vertex is (-4,18
