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
Thank you CPhill!
