Find the range, domain, and intercepts of the function. f(x)=3

<span>The domain is the set of all real numbers where the function is defined. In this case, the function would be defined everywhere, so all real numbers will satisfy this condition. The range is the domain of the inverse function, which will also have all real numbers as its range. Since this function can be stated as "y = 3" by replacing "f(x)", the intercept would be (0,3).</span>
