Question

Using complete sentences, explain how to find the average rate of change for f(x) from x = 4 to x = 7.

Answer 1

Even complete sentences are no help if you don't know what the
function f(x) is. Sadly, this is the very situation in which we find
ourselves, searching through the question to find the function,
fruitlessly, and coming up empty-handed.

As both Maimonides and Rashi pointed out more than eight
Centuries ago, you can't find the function's average rate of
change if you've never seen the function.
