There are 1 questions in this calculation: for each question, the 2 derivative of x is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ second\ derivative\ of\ function\ -0.0001x*3 + 0.0008{x}^{2} + 0.0298x + 22.034\ with\ respect\ to\ x：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &Primitive\ function\ = -0.0003x + 0.0008x^{2} + 0.0298x + 22.034\\&\color{blue}{The\ first\ derivative\ function：}\\&\frac{d\left( -0.0003x + 0.0008x^{2} + 0.0298x + 22.034\right)}{dx}\\=&-0.0003 + 0.0008*2x + 0.0298 + 0\\=&0.0016x + 0.0295\\\\ &\color{blue}{The\ second\ derivative\ of\ function:} \\&\frac{d\left( 0.0016x + 0.0295\right)}{dx}\\=&0.0016 + 0\\=&0.0016\\ \end{split}\end{equation} \]
