Thread: standard form

if you are given the vertex(-3,4) and lets say the information of the parabola is stretched by -2

i know the vertex form is y=-2(x+3)+4

but what is the standard form?

thanks

Doesn't the equation of a parabola contain a squared term? (I had assumed your original post was missing it due to a typo).
