Question 2818
<font face = "courier new">how do you graph {{{y = x^2-x-7}}} as a parabola?
`<font size = 4 font color = "green"><b>
Make a table of points:
`
`x | y
———————
-4 | 13
-3 |  5
-2 | -1
-1 | -5
`0 | -7
.5 | -7.25
`1 | -7
`2 | -5
`3 | -1
`4 |  5
`5 | 13
`
Plot these points and you have the graph:
`
{{{ graph( 200, 200, -5, 5, -10, 15, x^2-x-7) }}}
