There are 1 questions in this calculation: for each question, the 2 derivative of x is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ second\ derivative\ of\ function\ 0.0014{x}^{3} - 0.0485{x}^{2} + 0.3555x + 76.173\ with\ respect\ to\ x：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &Primitive\ function\ = 0.0014x^{3} - 0.0485x^{2} + 0.3555x + 76.173\\&\color{blue}{The\ first\ derivative\ function：}\\&\frac{d\left( 0.0014x^{3} - 0.0485x^{2} + 0.3555x + 76.173\right)}{dx}\\=&0.0014*3x^{2} - 0.0485*2x + 0.3555 + 0\\=&0.0042x^{2} - 0.097x + 0.3555\\\\ &\color{blue}{The\ second\ derivative\ of\ function:} \\&\frac{d\left( 0.0042x^{2} - 0.097x + 0.3555\right)}{dx}\\=&0.0042*2x - 0.097 + 0\\=&0.0084x - 0.097\\ \end{split}\end{equation} \]
