Find the domain of the function straight f left parenthesis straight x right parenthesis equals square root of straight x plus 2 end root

  1. x ≥ -2
  2. x ≥ -1
  3. x ≥ 0
  4. x ≥ 2

Hint:

Finding the domain of the function f(x)
For function apply greater than and equal to 0

The correct answer is: x ≥ -2


    Given that;
    the domain of the function straight f left parenthesis straight x right parenthesis equals square root of straight x plus 2 end root
    x + 2 ≥ 0
    x ≥ -2
    So, the domain of the function f(x) is x ≥ -2.
