There are 1 questions in this calculation: for each question, the 2 derivative of x is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ second\ derivative\ of\ function\ -0.158xxx - 9.353xx + 1013.65x - 5470.306\ with\ respect\ to\ x：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &Primitive\ function\ = -0.158x^{3} - 9.353x^{2} + 1013.65x - 5470.306\\&\color{blue}{The\ first\ derivative\ function：}\\&\frac{d\left( -0.158x^{3} - 9.353x^{2} + 1013.65x - 5470.306\right)}{dx}\\=&-0.158*3x^{2} - 9.353*2x + 1013.65 + 0\\=&-0.474x^{2} - 18.706x + 1013.65\\\\ &\color{blue}{The\ second\ derivative\ of\ function:} \\&\frac{d\left( -0.474x^{2} - 18.706x + 1013.65\right)}{dx}\\=&-0.474*2x - 18.706 + 0\\=&-0.948x - 18.706\\ \end{split}\end{equation} \]
