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?

what is it asking in the book?

- kaylaprincess

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.

ohhhh

- anonymous

u just take 2 points for example

- anonymous

when x=3 and when x=0

- anonymous

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

- anonymous

and u then u take another set of points and do the same

- anonymous

yea but its asking explain the situation between points

- anonymous

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

- anonymous

it would be decreasing

- anonymous

oh kk

im so confused...

gras can you help me?

- kaylaprincess

dude, chill, i have two people spewing information at me ! @Crazyandbeautiful

- anonymous

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

- anonymous

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

- anonymous

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

- anonymous

why do we have some increasing and some decreasing?

- anonymous

its because it is a parabola

- anonymous

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

- kaylaprincess

thank you!

- kaylaprincess

the flow is decreasing?
