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

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.So, the domain of the quadratic function is all real numbers, which can be written as: This means that you can substitute any real number for x in the function and it will still be valid.
