Question

ALGEBRA 2- If f(x)= √x-3 , which inequality can be used to find the domain of f(x)?

a. √x-3 ≥ 0
b. x-3 ≥ 0
c. √x-3 ≤ 0
d. x-3 ≤ 0

Answer 1

b, because you can't get the square root of a negative number

Answer 2

Option B

Explanation:

The given equation function is f(x) =
`√(x-3)`

Domain of this function will be determined by (x-3) ≥ 0

because square root of negative numbers is not defined.

Option B is the answer.
