What is the domain of the function y = 2 StartRoot x minus 6 EndRoot?

choices:

Negative infinity less-than x less-than infinity

0 less-than-or-equal-to x less-than infinity

3 less-than-or-equal-to x less-than infinity

6 less-than-or-equal-to x less-than infinity

Correct answer is D) 6 less-than-or-equal-to x less-than infinity

Step-by-step explanation:

Here we have   . We need to find domain of this function . Let's find out:

⇒

Since, Inside term of a square root is always greater then or equal to zero i.e.

⇒

Adding 6 both sides we get:

⇒

⇒

⇒

Therefore , Domain of function is all values of x greater then or equal to 6 i.e. . Correct answer is D) 6 less-than-or-equal-to x less-than infinity .
