There are 1 questions in this calculation: for each question, the 1 derivative of x is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ first\ derivative\ of\ function\ -ln(4 - 2x) - \frac{x}{2}\ with\ respect\ to\ x：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &Primitive\ function\ = -ln(-2x + 4) - \frac{1}{2}x\\&\color{blue}{The\ first\ derivative\ function：}\\&\frac{d\left( -ln(-2x + 4) - \frac{1}{2}x\right)}{dx}\\=&\frac{-(-2 + 0)}{(-2x + 4)} - \frac{1}{2}\\=&\frac{2}{(-2x + 4)} - \frac{1}{2}\\ \end{split}\end{equation} \]
