Seriously?  An AVERAGE of a constant function?  It's just 1.  Mark C and move on.  Never pause on a problem about average rate of change for a constant function.

shamil98 · Answer

for future reference for non-constant functions the formula for avg rate of change is :
 f(x) - f(a) / x - a

tkhunny · Answer

Of course, you mean [f(x) - f(a)] / (x - a).

The parentheses are not optional.
