Hey. Just a quick simple question. If i have a function such as:(adsbygoogle = window.adsbygoogle || []).push({});

[tex]

y = x^2

[/tex]

Id write the derivative of function y with respect to x as:

[tex]

\frac{{dy}}{{dx}} = 2x

[/tex]

What if the function of x was given as:

[tex]

f(x) = x^2

[/tex]

I know i could write the derivative as f'(x), but how would i write it in the form i used for the first function. Would this be what i should write:

[tex]

\frac{{df(x)}}{{dx}}

[/tex]

?

Would i write:

[tex]

\frac{{df}}{{dx}}

[/tex]

?

Does it even matter? Thanks for the quick advice

Dan.
