im so confused, i really need help understanding this.
what is it asking in the book?
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.
u just take 2 points for example
when x=3 and when x=0
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
and u then u take another set of points and do the same
yea but its asking explain the situation between points
so if we took when x=3 and when x=0
it would be decreasing
im so confused...
gras can you help me?
dude, chill, i have two people spewing information at me ! @Crazyandbeautiful
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?
the flow is decreasing?
