Question

I need help question

Answer 1

`f(x)=x^2-4x-94`

The diffrentiated function will be

`2x-4`

RULES FOR DIFFERENTIATION

`\begin{gathered} y=x^n \\ (dy)/(dx)=nx^(n-1) \end{gathered}`

Also

`\begin{gathered} y=kx \\ (dy)/(dx)=k \end{gathered}`

Also

`\begin{gathered} y=k \\ (dy)/(dx)=0 \end{gathered}`
