Please help need this done by tonight Kira wants to graph y = -3(x + 1)(x - 3). They think that it will be a
downward-opening parabola. They think that it has x-intercepts at (1, 0)
and (-3, O). They think that the axis of symmetry, or x-coordinate of the
vertex, will be halfway between 1 and -3, or -1. They substitute that into
their function, and get a y-coordinate of O. So, they graph their work, and
get what is shown. Explain whether you agree or disagree with Kira's work,
and if you disagree, what you think should be done differently. Answer
specifically about x-intercepts, the midpoint and axis of symmetry, and
vertex of the graph.
