The graphs of two rational functions f and g are shown. Which function must be given by the expression of 10/x-3? Explain how you know.

Function is y = 10/x-3
-Find the domain of function:
we have that
[tex]\begin{gathered} x-3\ne0 \\ x-3+3\ne0+3 \\ x\ne3 \end{gathered}[/tex]Therefore
[tex]x\in(-\infty,3)and(3,\infty)[/tex]-Then find the range, this is
[tex]y\in Real\text{ numbers}[/tex]So, is the graph of the function f(x).
Answer. rational function f
