    Next you would chose a value for x that is greater than -2 which is 0

    so now its 2(0)+9 which gives us 9 if we solve it and that is our y value

    giving us the coordinates for a point at (0,9) if we do a few more we get a graph for two of the columns

    This function works just like any other in the other two sections. For -6 < x < -2, the function is just y = 5, so for any x value in that range you'll get 5 as your result. Similarly, for any x < -6, y = 1.

    so any number would be -1 for the first two columns

    For the first two columns, you'll want to use different x values, but the y value will always be -1. So for example, the first two columns might look like: \[\left[ -6 | -1 \right]\]\[\left[ -7 | -1 \right]\]\[\left[ -8 | -1 \right]\]

    and the graph would be a horizontal line on y=-1 right
