what is the domain of the function y=square root of x +4
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 \(x \geq -4\)
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 \(x \geq -4\)
