Question

F(x)=-2(x+3)^2+5 what is the vertex, axis of symmetry, and is the parabola up or down and why?

Answer 1

Vertex: (-3,5)

Axis: x=-3

paranola: down

Explanation:

There is an easy way to tell whether the graph of a quadratic function opens upward or downward: if the leading coefficient is greater than zero, the parabola opens upward, and if the leading coefficient is less than zero, the parabola opens downward.
