expressing dy/dx in limit notation

[jlaird77]

Hello,
I am having a hard time tackling the following question.For any function y=f(x), express dy/dx using limit notation.Give a clear explanation for your given answer.How do you express slope using limit notation?

Think about the definition of a derivative.

\(\displaystyle \L\\f'(x)=\lim_{h\to\0}\frac{f(x+h)-f(x)}{h}\)

This is basic, basic stuff. Look up the definition of a derivative in any calc book or on line.

This is my first calculus course.I am having a hard time understanding the lingo!I didn't realize they were just asking for the formula.

Thanks again.
