This question is asking me to find the gradient function, $y'$ of the equation $y=5e^{3x}-6e^{-6x}$

I thought it was as simple as having $y=15e^{3x} - 36e^{-6x}$, however this isn't the gradient function. What am I doing so horribly wrong?

(yes, I'm really new to calculus).

Thanks!

    As a point of reference, the gradient is only the same as the derivative when considering functions of one variable. In multiple variables, the gradient is a vector of [partial derivatives](http://en.wikipedia.org/wiki/Partial_derivative).2012-10-19
