# Differentiating with respect to a negative variable.

Can we differentiate a function f(x) with respect to a negative variable? For example:Is this possible?

d/d(-x) [ax^2+bx+c] If this is wrong,why is that so?Please explain.

Yes you can do this.as derivative means rate of change of one variable with respect to another variable. Here it would mean how this polynomial changes with respect to -x.

You can even write this $$\frac{d(x^2)}{d(logx)}$$. So you must be thinking how to compute this derivative. put logx=t and replace x with exp(t). now you can easily find derivative in terms of t. Now again replace t with x.
