## Homework Statement

Find the derivative of f(x) = x using the definition of a derivative. (when Δx → 0)

## Homework Equations

(x + Δx) - x

--------------

Δx

## The Attempt at a Solution

I know the answer is 1. I graphed the function of f(x)=x and confirmed this, however the question states using the definition. I always end up cancelling the x, then substituting the 0 into Δx and ending up with 0/0.
