Question

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

Answer 1

Solution X≥0

Interval Notation [0, ∞)

Answer 2

Explanation:

Domain means all the values of x which are defined for the given function .

using the concept that we can only have positive values inside a square root we get a condition that

`x+4 \geq 0`

This simplifies to
`x\geq -4`

so domain os this function is [-4, 00)
