Question 1144137
<br>
The first four pairs lie on a straight line with slope 3.<br>
The last two pairs lie on a straight line with a slope of -3.<br>
So the slope of the graph changes sign at the fourth pair, (-2,0).<br>
So the five points can be on the graph of a function involving absolute values.  Specifically, with the slope changing from +3 to -3 at (-2,0),<br>
{{{f(x) = -3abs(x+2)}}}<br>
A graph, containing the points (-5,-9), (-4,-6), (-3,-3), (-2,0), and (-1,-3)...<br>
{{{graph(400,400,-6,2,-10,2,-3abs(x+2))}}}
