There are 1 questions in this calculation: for each question, the 2 derivative of x is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ second\ derivative\ of\ function\ -0.0002x*3 + 0.0077x*2 - 0.0272x + 5.2213\ with\ respect\ to\ x：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &\color{blue}{The\ first\ derivative\ function：}\\&\frac{d\left( -0.0006x + 0.0154x - 0.0272x + 5.2213\right)}{dx}\\=&-0.0006 + 0.0154 - 0.0272 + 0\\=&-0.0124\\\\ &\color{blue}{The\ second\ derivative\ of\ function:} \\&\frac{d\left( -0.0124\right)}{dx}\\=&0\\ \end{split}\end{equation} \]
