What is the domain of this quadratic function?

y=x^2–8x+16

1 answer

The domain of a quadratic function, or any polynomial function, is all real numbers. Thus, for the quadratic function \( y = x^2 - 8x + 16 \), the domain is:

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

This means you can use any real number as an input for \( x \).
