What is the domain of the function ? (1 point)

The domain of the function is all real numbers, as there are no restrictions on the values that can take. This means you can substitute any real number into the function and still get a valid output. In interval notation, this is expressed as .

Understanding the properties of polynomial functions can also shed light on their domains. Polynomials like are continuous and smooth, meaning they won’t have breaks, gaps, or asymptotes. This characteristic ensures that their domain is always the entire set of real numbers.
