I never done this, I never tried to find an average rate, I know who can help though, he is good at math (unlike me)
@Hero please help.

Okay! I'm usually really good at math, but trying to cram all this in before the end of December and not really having someone to teach it to me is like D:

The average rate of change of a function between two points is

A= (F(b) - (Fa))/B-A

schrodingers_cat · Answer

It is just simply they slope of the line connecting the two points.

Hope this helps :)

anonymous · Answer

So what's f mean in that equation? And I'm assuming A and B are the coordinates of the points? I read the lesson and it didn't make sense at all to me.

schrodingers_cat · Answer

Its the function evaluated at points A and B.

The way you approach this question depends on what level of math you are taking, what class are you in?

schrodingers_cat · Answer

However, you can just your graph to get those values of y at both x = -2 and 0.

Algebra 2, honors. I'm on logarithms right now.

Does this help?

anonymous · Answer

At -2, it's -4; at 0, it's -1. So where do I plug them in at?

schrodingers_cat · Answer

So, the function evaluated at  x =-2 is -4 and that would be f(a). At x =0 its -1 so that would be f(b). With -2 = a and 0 = b

schrodingers_cat · Answer

So, (-1 - -4)/(0 - -2) = 3/2

anonymous · Answer

Okay, so it's ysub2-ysub1/xsub2-xsub1 ?
