findsAs given by the question
There are given that the function
[tex]C(x)=20x+(\frac{2000}{x})[/tex]Now,
The domain of the given function is:
The domain of the given function that finding where the expression is defined.
So,
The defined expression in the interval notation is shown below:
[tex](-\infty,0)\cup(0,\text{ }\infty)[/tex]
