Answer:
The domain of the given function is [-5 ∞ )
Step-by-step explanation:
Given function,
[tex]f(x) =\sqrt{x+5} - 1[/tex]
∵ f(x) is not defined if x + 5 < 0
That is, for the given function,
x ≥ -5
x ∈ [-5 ∞ )
Since, the domain of a function is the all possible input value,
Here, x represents the input value for the given function,
Hence, the domain of the given function is [ -5 ∞ )
