Question

PLEASE HELP
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 = x2 − 2x
y = −2x2 + 4x − 3

Answer 1

In the first equation, the direction of the parabola is upward, because the x2 term is positive, and the vertex is at (1,-1). In the second equation, the direction of the parabola is downward, because the x2 term is negative, and the vertex is at (1,-1).
Both of the equation's vertex is at (1,-1) and they both have 2 real solutions.
