There are 1 questions in this calculation: for each question, the 2 derivative of x is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ second\ derivative\ of\ function\ 3{x}^{2} + 2x - 5\ with\ respect\ to\ x：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &Primitive\ function\ = 3x^{2} + 2x - 5\\&\color{blue}{The\ first\ derivative\ function：}\\&\frac{d\left( 3x^{2} + 2x - 5\right)}{dx}\\=&3*2x + 2 + 0\\=&6x + 2\\\\ &\color{blue}{The\ second\ derivative\ of\ function:} \\&\frac{d\left( 6x + 2\right)}{dx}\\=&6 + 0\\=&6\\ \end{split}\end{equation} \]
