## Homework Statement

The problem is : take the derivative of (x - a)

## Homework Equations

Power Rule : f '(x) = r x^(r-1)

Difference Rule : f '(x) = g '(x) - h '(x)

## The Attempt at a Solution

This is such a simple problem but I don't understand how my solutions manual and Wolfram Alpha came to the answer. According to these sources the answer is 1.

However, because both variables in the expression are to a single power I was under the impression the derivative of each variable would equal 1, leading to (1 - 1) = 0

If you need any clarification, please let me know.
