There are 1 questions in this calculation: for each question, the 2 derivative of x is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ second\ derivative\ of\ function\ 2{e}^{(-3x)}\ with\ respect\ to\ x：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &\color{blue}{The\ first\ derivative\ function：}\\&\frac{d\left( 2{e}^{(-3x)}\right)}{dx}\\=&2({e}^{(-3x)}((-3)ln(e) + \frac{(-3x)(0)}{(e)}))\\=&-6{e}^{(-3x)}\\\\ &\color{blue}{The\ second\ derivative\ of\ function:} \\&\frac{d\left( -6{e}^{(-3x)}\right)}{dx}\\=&-6({e}^{(-3x)}((-3)ln(e) + \frac{(-3x)(0)}{(e)}))\\=&18{e}^{(-3x)}\\ \end{split}\end{equation} \]
