There are 1 questions in this calculation: for each question, the 2 derivative of x is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ second\ derivative\ of\ function\ -0.0025{x}^{3} + 0.0552{x}^{2} - 0.4332x + 12.499\ with\ respect\ to\ x：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &Primitive\ function\ = -0.0025x^{3} + 0.0552x^{2} - 0.4332x + 12.499\\&\color{blue}{The\ first\ derivative\ function：}\\&\frac{d\left( -0.0025x^{3} + 0.0552x^{2} - 0.4332x + 12.499\right)}{dx}\\=&-0.0025*3x^{2} + 0.0552*2x - 0.4332 + 0\\=&-0.0075x^{2} + 0.1104x - 0.4332\\\\ &\color{blue}{The\ second\ derivative\ of\ function:} \\&\frac{d\left( -0.0075x^{2} + 0.1104x - 0.4332\right)}{dx}\\=&-0.0075*2x + 0.1104 + 0\\=&-0.015x + 0.1104\\ \end{split}\end{equation} \]
