Question

is y=-2x² a opening

equation of parabola

Answer 1

Answer:

If a>0 in f(x)=ax2+bx+c, the parabola opens upward. In this case the vertex is the minimum, or lowest point, of the parabola. A large positive value of a makes a narrow parabola; a positive value of a which is close to 0 makes the parabola wide.

Answer 2

yes it is a parabolic equation
