The average rate of change of f(x)=3x+9 is 9.
True of False?

Question

The average rate of change of f(x)=3x+9 is 9.
True of False?

anonymous · Answer

False.

anonymous · Answer

The equation is in slope-intercept form: f(x)=mx+b. M is the slope. And in the equation, 3x+9, the 3 is in the M spot. So the rate of change is 3.

What kind of question is this? Calculus?

anonymous · Answer

It's more Algebra.

anonymous · Answer

Oh ok, I didn't see it like that! Thank you :) 
and its suppose to be Algebra :)

anonymous · Answer

Assuming that this is a simple linear equation, there is no calculus involved.

ness9630 · Answer

Just asking, they have average rate of change in calc too.

anonymous · Answer

hey keith can u plz help me on my problem

anonymous · Answer

That's because with a linear equation, the average rate of change is the same as the instantaneous rate of change which is the slope

anonymous · Answer

keith can u plz help me on my question plz

anonymous · Answer

and @Ness9630 , Calculus focuses more with regards to slope on the instantaneous aspect. And I would love to @magie22. This one?
