There are 1 questions in this calculation: for each question, the 2 derivative of x is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ second\ derivative\ of\ function\ -0.0011{x}^{3} + 0.0226{x}^{2} - 0.9499x + 37.867\ with\ respect\ to\ x：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &Primitive\ function\ = -0.0011x^{3} + 0.0226x^{2} - 0.9499x + 37.867\\&\color{blue}{The\ first\ derivative\ function：}\\&\frac{d\left( -0.0011x^{3} + 0.0226x^{2} - 0.9499x + 37.867\right)}{dx}\\=&-0.0011*3x^{2} + 0.0226*2x - 0.9499 + 0\\=&-0.0033x^{2} + 0.0452x - 0.9499\\\\ &\color{blue}{The\ second\ derivative\ of\ function:} \\&\frac{d\left( -0.0033x^{2} + 0.0452x - 0.9499\right)}{dx}\\=&-0.0033*2x + 0.0452 + 0\\=&-0.0066x + 0.0452\\ \end{split}\end{equation} \]
