I know that x^2 is the shape of a parabola.
OpenStudy (anonymous):
average rate of change just means slope
OpenStudy (anonymous):
so just find the slope between (1,1) and (5,25)
OpenStudy (anonymous):
m = ysub2-ysub1/xsub2/xsub1
OpenStudy (anonymous):
how do you format that?

yes

at the bottom of the page, there is button that says Equation. Click on it
OpenStudy (anonymous):
so I understand where you got the 1 and 5
how did you get 1,1 and 5,25?
OpenStudy (anonymous):
solving for slope is not difficult :)
OpenStudy (anonymous):
f(1) = 1^2 = 1
f(5) = 5^2 = 25
so (1,1) and (5,25)

\[25-1/5-1 = 24/4 = 6\]
OpenStudy (anonymous):
probably a better way to format that :)
OpenStudy (anonymous):
average rate of change is 6
OpenStudy (anonymous):
yes
OpenStudy (anonymous):
I am still getting the hang of the format

how do you make it look all nice?
OpenStudy (anonymous):
there are bunch of formats and symbols on the right and side when you click Equation button. Just play with it
OpenStudy (anonymous):
that helped out
thanks!
