Let
\(f(x) = \frac{3x - 7}{x + 1}.\)
Find the domain of f. Give your answer as an interval.

We have a vertical asymptote at  x  = -1   because this value makes the  denominator undefined....

 

So....the  domain  iss (-inf, -1 ) U (-1, inf)

 

See my previous answer  as to the range of this rational function for the  graph

 

 

cool cool cool
