Question

By comparing
f(x) = 3(x − 0)2 − 5
with
f(x) = a(x − h)2 + k,
we see that the vertex is

Answer 1

The vertex is always (h, k). So in this case it will be (0, -5)

Answer 2

and a=?

Answer 3

A doesn't matter, the vertex only involves h, k

Answer 4

I ask because my math problem is asking for it....
