y = −x2 − 1; y = 2x2 − 4.

1.	y = −x2 − 1; y = 2x2 − 4.
Answer» The solution to the system of equations giveny = −x² − 1; y = 2x² − 4,is (-1, -2) and (1, -2). Quadratic equations are equations with degrees equal to two. They can have at most two roots. A system of two quadratic equations can have at most two solutions, that is, the points where they intersect.
