@hartnn are you busy?

hartnn · Answer

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

hartnn · Answer

so for your question
from -2 to 2 means
a=-2
b=2

hartnn · Answer

$\Large \dfrac{f(2)-f(-2)}{2-(-2)}$

hartnn · Answer

can you get f(2) and f(-2) from the graph ?

kitkat16 · Answer

If I follow the graph it would be 4 yes? I'm not sure if I'm understanding how to read the graph.
