**1. Homework Statement**

Use the limit definition to find the derivative of the function.

f(x)= 1/(2x-4)

**2. Homework Equations**

f(x+h)-f(x)/h

**3. The Attempt at a Solution**

ok so first i plugged it all in..

(1/(2(x+h)-4))-(1/(2x-4)) / h

from here i was going to do fly-by with the two top fractions but for some reason nothing cancels out...

so please help this is due for me by monday!! lol

(any help appreciated)
