Answer
Select any three of the following four statements:
1. $r$ is a real zero of a polynomial function $f$.
2. $r$ is an $x$-intercept of the graph of $f$.
3. $x-r$ is a factor of $f.$
4. $r$ is a solution to the equation $f(x)=0$
Work Step by Step
After the definition of a real zero,
(If $f$ is a function and $r$ is a real number for which $f(r)=0,$ then $r$ is called a real zero of $f.$)
The text lists four equivalent statements (given in the answer).
