The definition is
First I did the numerator:
Then I put the denominator in:
Then the limit gives me
Did I do this correctly? Thank you.
Using the definintion, find the derivative of f(x) = 1/x.

The definition is=\lim_{h \rightarrow 0}\frac{f(x+h)-f(x)}{h})
First I did the numerator:
}-\frac{x+h}{x(x+h)})
})
Then I put the denominator in:
}\right)}{h})
}=\frac{-1}{x(x+h)})
Then the limit gives me
