Question

How do I convert f(x)=x^2-4 to vertex form?

Answer 1

hmm its already in vertex form

Answer 2

middle term is 0

--> (x-0)^2 -4

vertex at (0,-4)

Answer 3

Ohh, Alright! Thanks

Answer 4

But then is it already in standard form also?

Answer 5

yes it is....i guess technically you would write it as (x-0)^2 for vertex form though its not needed
