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.
\n" ); document.write( "y = x^2 – 1
\n" ); document.write( "If x=0, y=-1
\n" ); document.write( "If x=1, y=0
\n" ); document.write( "If x=2, y=3
\n" ); document.write( "If x=-1,y=0
\n" ); document.write( "If x=-2,y=3
\n" ); document.write( "--------------------
\n" ); document.write( "opens up because the points go up centered at (0,-1)
\n" ); document.write( "------------------
