Question
Determine if the statement is true or false.Suppose that $f(x)$ is a polynomial, and that $a$ and $b$ are real numbers where $a<b$. If $f(a)<0$ and $f(b)<0$, then $f(x)$ has no real zeros on the interval $[a, b]$.
Step 1
We have a polynomial function $f(x)$ and two real numbers $a$ and $b$ such that $a<b$. It is given that $f(a)<0$ and $f(b)<0$. Show more…
