Question

The domain of f(x) is the set of all real values except 7, and the domain of g(x) is the set of all real values except –3. Which of the following describes the domain of (g circle f) (x)?

Answer 1

Answer:

the domain of  f∘g (x) is the set of all real values except -3 and 7

Step-by-step explanation:

the domain f∘g consists of only those inputs in the domain of g that produce outputs from g belonging to the domain of f.

The domain of g(x) consists of all real numbers except x=-3

The domain of f(x) is the set of all real values except 7. So we need to exclude from the domain of g(x) the value of x for which g(x)= 7.

So  the domain of  f∘g (x) is the set of all real values except -3 and 7
