Question

Average rate of change question:

Answer 1

@SolomonZelman

Answer 2

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.

Answer 3

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:

Answer 4

The average rate of change of a function between two points is

A= (F(b) - (Fa))/B-A

Answer 5

It is just simply they slope of the line connecting the two points.

Hope this helps :)

Answer 6

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.

Answer 7

Its the function evaluated at points A and B.

Answer 8

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

Answer 9

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

Answer 10

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

Answer 11

Does this help?

Answer 12

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

Answer 13

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

Answer 14

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

Answer 15

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