Question

Compare and contrast the two quadratic equations below. In order to receive full credit, use complete sentences to describe the following:
The direction each parabola opens

The vertex of each parabola

y = x^2 - 2x
 y = -2x^2 + 4x - 3

hero · Answer

y = x^2 - 2x opens upward
 y = -2x^2 + 4x - 3 opens downward

use x = -b/2a to find the x coordinate of vertex, then insert that into original parabola to find y
