Question

Find the domain of the function.

y = 5
`√(x)`

Answer 1

[0, infinity)

Explanation:

The domain is including all numbers from 0 to infinity.

The reason negative numbers are not included is because of the
`√(x)`. A negative number cannot be included there, otherwise it would be what's called an "imaginary number" (i).

Therefore, every number besides negative numbers are included in the domain.
