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