## anonymous one year ago Find the average rate of change for the given function from x = −2 to x = 1. A -1 B 1 C -3 D3

You would have to go with choice E. Not enough information. Hint: No function was given.

2. freckles

if you did have a function let's call it f then the average rate of change from x=-2 to x=1 is given by: $\frac{f(1)-f(-2)}{1-(-2)}$

What about a graph that has one point on (5,0) and another on (0,-5)

4. anonymous

is that enough info?

5. freckles

is it a linear function?

6. anonymous

yea

7. freckles

ok well if it is a linear function the slope would be the same for any two points you chose on that line just find the average rate of change using the points you gave

8. freckles

aka slope

k thanks m8
