Draw accurate graphs of , ,  on the same set of axes. Label the intercepts.   

  1. In the equation , what does the tell you about the graph?

    This is in the form . What does stand for?

  2. Is the in also the slope? Explain.

    Increasing line & 2 upward parabolas share the point (0, comma 5). Additional point on line, (negative 1, comma 1). Vertex of both parabolas, is shared point, and 1 is skinnier than the other

    Is this in the form, ?

    is the stretch factor. This is a curve, so it does not have a constant slope.
