Question

Find the average rate of change for the given function from x = −2 to x = 1.

A -1
B 1
C -3
D3

Answer 1

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

Answer 2

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:
\[\frac{f(1)-f(-2)}{1-(-2)}\]

Answer 3

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

Answer 4

is that enough info?

Answer 5

is it a linear function?

Answer 6

yea

Answer 7

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

Answer 8

aka slope

Answer 9

k thanks m8
