-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 ) = x + 5 3
It is a fraction , in which the denominator cannot be zero, thus:
x + 5 = 0
x = − 5
Which means that number -5 is not a part of the domain of the function.

The number that is not part of the domain of the function f ( x ) = x + 5 3 is − 5 . This is because the denominator becomes zero when x = − 5 , making the function undefined at that point. Thus, the domain includes all real numbers except − 5 .
