The graph of \(f\) and the line have always a common point for all \(m\in\left(-\infty;-3\right)\).
The graph of \(f\) and the line have always a common point for \(m =-3\).
The graph of \(f\) and the line have always a common point for all \(m\in\left(-3;+\infty\right)\).
The graph of \(f\) and the line have always a common point for all \(m\in\mathbb{R}\).
