A paint wholesaler uses the function f(x)=2\sqrt{x}f(x)=2 x

to determine the cost, in dollars, to buy xx gallons of paint. Find and interpret the given function values and determine an appropriate domain for the function.
Round your answers to the nearest cent.

f(0)=f(0)=
, meaning the cost of buying
gallons of paint would be $
. This interpretation
in the context of the problem.
f(70)=f(70)=
, meaning the cost of buying
gallons of paint would be $
. This interpretation
in the context of the problem.
f(58.5)=f(58.5)=
, meaning the cost of buying
gallons of paint would be $
. This interpretation
in the context of the problem.
Based on the observations above, it is clear that an appropriate domain for the function is
.
