Respuesta :
domain is found by solving x-4>=0
the range is found by thinking of the outputs
the outputs can range from 0 to infinity hope this helps
Answer:
The domain of the function are real values of x for which [tex]x \geq -4[/tex]
Step-by-step explanation:
The square root function is:
[tex]g(x) = \sqrt{f(x)}[/tex]
It's domain is:
real values of x, for which[tex]f(x) \geq 0[/tex]
In this problem, we have that:
[tex]y = \sqrt{x + 4}[/tex]
So
[tex]f(x) = x + 4[/tex]
[tex]f(x) \geq 0[/tex]
[tex]x + 4 \geq 0[/tex]
[tex]x \geq -4[/tex]
The domain of the function are real values of x for which [tex]x \geq -4[/tex]
