Question 20 3 pts Find the derivative. 9 4 y = 36 4 dy dx O 23 + - 4x

Answer 1

we have the following:

`y=(9)/(x^4)-(4)/(x)`

derivate:

`\begin{gathered} y^(\prime)=9(d)/(dx)((1)/(x^4))-4(d)/(dx)((1)/(x)) \\ y^(\prime)=9\cdot((-6)/(x^5))-4((-1)/(x^2)) \\ y^(\prime)=-(36)/(x^5)+(4)/(x^2) \end{gathered}`

therefore, the correct answer is first option
