Question 786121
{{{ graph( 300, 200, -5, 6, -25, 25, x^2 -9) }}} 

You need an accurate graph to tell.  The graphs on this site don't make it easy to see the high and low points.  The lowest point in that range is -9, when x=0.  The highest point is 25, when x=6.  The range, in the domain -5<=x<=6, is -9<=y<=25.
