$\"\"$

Observe figure $\"\"$ : The intersection points occurs only between $\"\"$ and $\"\"$ .

Because, for $\"\"$ the graph of $\"\"$ does not intersects the graph of $\"\"$ and for $\"\"$ the graph of $\"\"$ does not intersects the graph of $\"\"$ .

Therefore, there is no further points of intersection (and therefore solutions) exist in figure $\"\"$ for $\"\"$ or $\"\"$ .
