Answer:
The domain of the function is 0 less-than-or-equal-to x less-than infinity ⇒ 3rd answer
Step-by-step explanation:
The domain of the function f(x) = y is all the values of x which make the function defined
∵ [tex]y=\sqrt{x}+4[/tex]
- There is no square root for negative number, that means x
must be non-negative number
∵ The non negative numbers start from zero till infinity
∴ 0 ≤ x < ∞
∴ x must be greater than or equal zero and less than infinity
- Values of x are the domain of the function
∴ The domain of the function is 0 ≤ x < ∞
The domain of the function is 0 less-than-or-equal-to x less-than infinity
