There are 1 questions in this calculation: for each question, the 2 derivative of x is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ second\ derivative\ of\ function\ -0.0008{x}^{3} + 0.0107{x}^{2} - 0.0885x + 77.192\ with\ respect\ to\ x：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &Primitive\ function\ = -0.0008x^{3} + 0.0107x^{2} - 0.0885x + 77.192\\&\color{blue}{The\ first\ derivative\ function：}\\&\frac{d\left( -0.0008x^{3} + 0.0107x^{2} - 0.0885x + 77.192\right)}{dx}\\=&-0.0008*3x^{2} + 0.0107*2x - 0.0885 + 0\\=&-0.0024x^{2} + 0.0214x - 0.0885\\\\ &\color{blue}{The\ second\ derivative\ of\ function:} \\&\frac{d\left( -0.0024x^{2} + 0.0214x - 0.0885\right)}{dx}\\=&-0.0024*2x + 0.0214 + 0\\=&-0.0048x + 0.0214\\ \end{split}\end{equation} \]
