Can you find the vertex of ?

Your function is stretched and shifted version of . Identify the transformation and you will see where the new vertex is. - Jul 16th 2011, 05:41 PMHallsofIvyRe: Inverted Parabola
No, you do NOT set y equal to 0. That would give the y-intercept which, in general, has nothing to with the vertex.

Since a square is never 0, , is never less than -3. It**is**-3 when the**square**is 0- that is, when y+ 1= 0. - Jul 16th 2011, 07:01 PMskokerRe: Inverted Parabola
it helps to write out the standard form formula. then you can see what its telling you.

vertex=(h,k)

you also know your values are inverted.
