A parabola that has a maximum = -3 at x = -11. Give four things that are true about the parabola based on this information. Include in your discussion the number of x-intercepts (if any) for the parabola.

Answer 1

1) The parabola opens downwards because it is a maximum value
2) The vertex is located at the maximum value (-3, -11)
3) There are no zeros because the parabola opens downwards and has a maximum value below the x-axis.
4) YOUR TURN... sketch the parabola and describe what you see : )
