If you input any number less than 4, the output would be a complex number, and would not count toward the domain. The function provided in the video would be undefined for real numbers less than 4. WebSame reply as provided on your other question. It is not saying that the roots = 0. A root or a zero of a polynomial are the value (s) of X that cause the polynomial to = 0 (or make Y=0). It is an X-intercept. The root is the X-value, and zero is the Y-value. It is not saying that imaginary roots = 0. 2 comments. puffins clyst heath
