Question

Calculus 1 homework help

Answer 1

The derivation is very difficult to write using this editor, but the answer is 12(x+a)/(ax)^2.

To get there write out the expression for the difference, get (ax)² as common denominator, then divide out the

x-a from the denominator...and there you will have it.
