What is the domain of the function f(x)=x−16? f(x)=x−16?
the function is defined when f(x) is greater than or equal to 0, therefore the domain is f(x)≥0.
the function is defined only when x−16 is greater than 0, therefore the domain is x> 16.
the function is defined for any value of x, therefore the domain is all real numbers.
the function is defined only when x is greater than or equal to 0, therefore the domain is x≥0.
