Question

Use the graph below to answer the following question:

What is the average rate of change from x = –1 to x = 1?

-4
-2
2
4

Answer 1

If you look at your slope (or use the method of rise over run) on the graph, you would see that it is up (rising) 4 places from the vertex, and then over (running) 1 place to the right; that means the slope is 4 or 4/1. So your answer is D.

Answer 2

its 2 because its goes from -1 to 0 then 1

Answer 3

Thanks so much!
