Question

What is the domain of the function y=square root of x +4

Answer 1

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 2

Answer:

The domain of the function are real values of x for which $x \geq -4$

Step-by-step explanation:

The square root function is:

$g(x) = \sqrt{f(x)}$

It's domain is:

real values of x, for which$f(x) \geq 0$

In this problem, we have that:

$y = \sqrt{x + 4}$

So

$f(x) = x + 4$

$f(x) \geq 0$

$x + 4 \geq 0$

$x \geq -4$

The domain of the function are real values of x for which $x \geq -4$
