What is the domain of the quadratic function g(x)=x^2+7x+10 ? 8.

<br /><br />The domain of a function is the set of all possible input values (often the "x" variable), which produce a valid output from a particular function. For a quadratic function, the domain is all real numbers because you can substitute any real number for x and the function will still be valid.<br /><br />So, the domain of the quadratic function $g(x)=x^{2}+7x+10$ is all real numbers, which can be written as:<br /><br />\[(-\infty, \infty)\]<br /><br />This means that you can substitute any real number for x in the function $g(x)$ and it will still be valid.
