Do we know if one is the vertex?

anonymous · Answer

well we know standard form is x^2

anonymous · Answer

@Austin6i6 - No. This was all the information I was given.

anonymous · Answer

so if you input -3 you should get 9 because 3^2 = 9
but we don't so what can we do to x^2 to get are desired output of 8
