Answer

Answer:

$f(x_1)\neq f(x_2)$

Explanation:

Step1: Recall one - to - one definition

A function $y = f(x)$ is one - to - one if for any two distinct elements $x_1$ and $x_2$ in the domain of $f$, the function values $f(x_1)$ and $f(x_2)$ are also distinct. That is, if $x_1\neq x_2$, then $f(x_1)\neq f(x_2)$.
