Answer:
The derivative of the function is 3.
Step-by-step explanation:
The derivative of [tex]a*x^{n}[/tex] is [tex]a*n*x^{n-1}[/tex]. The derivative of 20x is 20, for example. The derivative of [tex]40x^{4}[/tex] is [tex]160x^{3}[/tex].
In this problem
It aks the derivative of a function, which is 3x. Applying the rule that is explained above, we have that the derivative of 3x is 3.
So the derivative of the function is 3.
