There are 1 questions in this calculation: for each question, the 2 derivative of x is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ second\ derivative\ of\ function\ 9273.15x - 2225.56{x}^{2} + 148.37{x}^{3}\ with\ respect\ to\ x：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &Primitive\ function\ = 9273.15x - 2225.56x^{2} + 148.37x^{3}\\&\color{blue}{The\ first\ derivative\ function：}\\&\frac{d\left( 9273.15x - 2225.56x^{2} + 148.37x^{3}\right)}{dx}\\=&9273.15 - 2225.56*2x + 148.37*3x^{2}\\=& - 4451.12x + 445.11x^{2} + 9273.15\\\\ &\color{blue}{The\ second\ derivative\ of\ function:} \\&\frac{d\left( - 4451.12x + 445.11x^{2} + 9273.15\right)}{dx}\\=& - 4451.12 + 445.11*2x + 0\\=&890.22x - 4451.12\\ \end{split}\end{equation} \]
