You can put this solution on YOUR website! No, I'm assuming that by "not stretched", he meant the coefficient in front of the quadratic term is or else you would need more information.

Vertex form of the equation of a parabola:
Since the parabola was NOT STRETCHED, and is concave down, then
With vertex being (4, - 2), and a being - 1, becomes: __________
