Let f(x)= (3x-7) / (x+1)

Find the domain of f. Give your answer using interval notation. 

Note: The numerator is (3x-7) and the denominator is (x+1)

Thanks in advance.

Every  x  is in the domain  except the x  that  make the denominator   =   0 

 

This is   -1

 

So

 

Domain  is

 

-inf < x <  -1   U   -1 < x  <  inf
