Sagot :
-5, you never want the denominator to equal zero or else it doesnt exist!
x+5=0
x=-5
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:
[tex]f(x) = \frac{3}{x + 5}[/tex]
- It is a fraction, in which the denominator cannot be zero, thus:
[tex]x + 5 \neq 0[/tex]
[tex]x \neq -5[/tex]
- Which means that number -5 is not a part of the domain of the function.
