Intersection point/Functions/x-1/2 over x/Exercise

1. Sketch the graphs of the functions

   $f\colon \mathbb {R} _{+}\longrightarrow \mathbb {R} ,x\longmapsto x-1,$

   and

   $g\colon \mathbb {R} _{+}\longrightarrow \mathbb {R} ,x\longmapsto {\frac {1}{x}},$

2. Determine the intersection points of these graphs.
