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

 

Thank you so much!

The domain is the set of all real numbers that are allowable replacements for x.

The only number not allowed is -1, because this number makes the denominator zero.

So the domain is:  (-infinity, -1)  union  (-1, infinity).
