# Math Help - Derivative of specific point

Derivative of specific point

Function: x^3+2/x at the point -2,3

I know the derivative is

$\frac{x^3+2}{x} ~?$

How would I insert the point into that function?

Why in the world are you so lazy as to not use grouping symbols?
Is it $x^3+\frac{2}{x}\text{ or }\frac{x^3+2}{x}~?$

Why in the world are you so lazy as to not see on which of those options the point (-2, 3) lies?
It's the latter, by the way.

Please be more careful with your language. There is a HUGE difference between a derivative AT a point and a derivative OF a point. The latter probably doesn't exist.
