Question

What is the vertex of `y= x^2– 12`?

Answer 1

`(0,-12)`

Explanation:

This is really just the graph of `y=x^2` shifted down by 12 units.

This means that for `y=x^2-12,` the vertex will be similar to that of `y=x^2,` with the `y-`coordinate being `12` smaller.

The vertex of `y=x^2` is `(0, 0).` Here, the vertex is `(0, 0-12)=(0,-12)`
