Verified Answer :

-5, you never want the denominator to equal zero or else it doesnt exist!

x+5=0
x=-5

Using the concept of the domain, it is found that number -5 is not a part of the domain of the function.

---------------------------

  • The domain of a function is the set that contains all possible input values.
  • For a function f(x), the input is x.

The function given is:

\(f(x) = \frac{3}{x + 5}\)

  • It is a fraction, in which the denominator cannot be zero, thus:

\(x + 5 eq 0\)

\(x eq -5\)

  • Which means that number -5 is not a part of the domain of the function.
