f%28x%29=+2x%2B3
if the line is never ending, then the domain/range would be all real numbers since no number would stop the graph from going into infinity
+graph%28+600%2C+600%2C+-10%2C+10%2C+-10%2C+10%2C2x%2B3%29+
so,
the domain: all real numbers
(-infinity,infinity)
and range:all real numbers
(-infinity,infinity)
