Question

What is the domain of this quadratic function?
y=x2+2x–24

Answer 1

The domain of a quadratic function is the set of all possible input values (x-values) for which the function is defined. Since a quadratic function, such as \( y = x^2 + 2x - 24 \), is defined for all real numbers, the domain is:

\[
\text{Domain: } (-\infty, \infty)
\]

This means that you can input any real number for \( x \) into the function.
