Question

What is the average rate of change from x = 0 to x = −2?


Answer choices:
a) 2
b) 3
c) -3
d) 0

Answer 1

whats your function f(x) ?

Answer 2

Average rate of f(x) from a to b is
\(\Large \dfrac{f(b)-f(a)}{b-a}\)

a= 0, b =-2

so you just need to find
f(0) and f(-2)

Answer 3

would you like to see a picture of the graph they want me to use to solve this?

Answer 4

if you have any problems finding out f(0) and f(-2)
then i can help you with it if i have the graph :)

Answer 5

ok hold on :)

Answer 6

so can you find f(0) ?
its the y co-ordinate (when x=0)
where the graph cuts the y -axis

Answer 7

-4?
