Question

what is the domain function of y=√x+4

Answer 1

[0, ∞) is the domain for the equation y=√x+4. The solution is x≥0

Answer 2

Answer:

The domain of the function is $[-4,\infty)$.

Step-by-step explanation:

Domain is the set of all possible inputs for which the function is defined.

The given function is

$y=\sqrt{x+4}$

It is a radical function. The function is defined if the expression inside the radical greater than or equal to zero.

$x+4\geq 0$

Subtract 4 from both the sides.

$x+4-4\geq 0-4$

$x\geq -4$

The domain of the given function is

$Domain=\{x|x\geq -4\}=[-4,\infty)$

Therefore the domain of the function is $[-4,\infty)$.
