Answer

Maximum: When in the function y=a$x^{2}$+bx+c, a$\gt$0 Minimum: When in the function y=a$x^{2}$+bx+c, a$\lt$0

Work Step by Step

The vertex of a parabola is a minimum point when in the function y=a$x^{2}$+bx+c, a$\gt$0. In this case, the parabola will open up, and the vertex will be the minimum point. The vertex of a parabola is a maximum point when in the function y=a$x^{2}$+bx+c, a$\lt$0. In this case, the parabola will open down, and the vertex will be a maximum point.
