Identify the [math]x[/math]-intercepts, the axis of symmetry, and the vertex of the quadratic [math]f(x) = (x + 5)(x + 2)[/math]. Use this information to graph the function.
[list=1] [*]Identify the [math]x[/math]-intercepts and plot the points. [*]Determine the axis of symmetry to find the vertex. [*]Graph the zeros, the vertex, and the axis of symmetry of the given equation. [*]Sketch the function based on the zeros and the vertex.
