The graph below plots a function f(x):
If x represents time, the average rate of change of the function f(x) in the first three seconds is ___.
OpenStudy (joannablackwelder):
Average rate of change is slope. Can you find slope?
OpenStudy (anonymous):
yeah but it doesn't sound right -6/4
OpenStudy (joannablackwelder):
Hm, that's not what I get. How did you get that?
OpenStudy (anonymous):
