There are 1 questions in this calculation: for each question, the 1 derivative of x is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ first\ derivative\ of\ function\ -4{x}^{4} + 3{x}^{2} - 15x + 5\ with\ respect\ to\ x：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &Primitive\ function\ = -4x^{4} + 3x^{2} - 15x + 5\\&\color{blue}{The\ first\ derivative\ function：}\\&\frac{d\left( -4x^{4} + 3x^{2} - 15x + 5\right)}{dx}\\=&-4*4x^{3} + 3*2x - 15 + 0\\=&-16x^{3} + 6x - 15\\ \end{split}\end{equation} \]
