Question 89087: Describe what the graph of the following equation would look like, by providing a set of five x/y values centered around the axis of symmetry, stating the x-intercepts, and explaining whether the parabola would open up or open down and how you know.
y = x^2 – 1

You can put this solution on YOUR website! Describe what the graph of the following equation would look like, by providing a set of five x/y values centered around the axis of symmetry, stating the x-intercepts, and explaining whether the parabola would open up or open down and how you know.
y = x^2 – 1
If x=0, y=-1
If x=1, y=0
If x=2, y=3
If x=-1,y=0
If x=-2,y=3
--------------------
opens up because the points go up centered at (0,-1)
------------------
