Where are you stuck, brother?

frostarmy05 · Answer

i can't find the Average Rate of Change

3mar · Answer

Do you want it from "limits" or from "the first derivative" of the function?

frostarmy05 · Answer

i don't know thats all the question asks me

3mar · Answer

Are you studying "limits" or "derivatives"?

frostarmy05 · Answer

limits...i think

3mar · Answer

Great!

so are you familiar with that?

frostarmy05 · Answer

yes i have been seeing it in my pass math tests

3mar · Answer

So can you substitute with x=2 in f(x+h) and with x=0 in f(x) and divide by $h=\Delta x=x_2-x_1$?
Do it and share your works, please!
