help me with quadratics? (x+3)(x-3) x = 3 y = -9 I have graphed. i just dont understand : describe if the average rate of change is increasing or decreasing, from left to right. Justify your observations with calculations. like how do i do/start this?

    explain whether the average rate of change is increasing or decreasing, from left to right. Justify your observations by comparing the slopes calculated between at least three different pairs of points.

    look at the graph when x=0...its is at -9....when x=3...it is at 0....if u follow the line it is increasing between those points

    so if we took when x=3 and when x=0

    make a table for that equations plug in x-values -4 through -3...the y values should be decreasing

    whereas if u plug in a different set of values they increase like from x=0,x=1,x=2,x=3...y values for these are -9,-8,-5...they are increasing

    x=-4,x=-3,x=-2 y values:7,0,-5 therefore decreasing

    why do we have some increasing and some decreasing?

    its because it is a parabola

    it has a loop...so they just want u to pick 3 pairs of point and establish the flow: is it increasing?decreasing?
