The domain<span> is all real numbers and the range is all real numbers f(</span>x) such that f(x<span>) ≥ 7. C) The </span>domain<span>is all real numbers </span>x<span> such that </span>x<span> ≥ 0 and the range is all real numbers. Incorrect. Negative values can be used for </span>x<span>, but the range is restricted because </span>x2<span> ≥ 0.</span>
