What is the domain of the function y = StartRoot x EndRoot + 4?
Negative infinity less-than x less-than infinity
Negative 4 less-than-or-equal-to x less-than infinity
0 less-than-or-equal-to x less-than infinity
4 less-than-or-equal-to x less-than infinity

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

∵

- 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
