Question

What is the domain of this function
y= sqrt of x

Answer 1

Domain: [0, ∞)

Explanation:

Domain is the set of x-values that can be inputted into function f(x).

Our f(x) = √x

We know that we cannot have a negative under the square root. Therefore, we know that our x-values span from 0 to infinity:

[0, ∞) or x ≥ 0
