Question

Which function has the domain x greater-than-or-equal-to negative 11?

Answer 1

Given:

Consider the below figure attached with this question.

To find:

The function that has the domain $x\geq -11$.

Solution:

We know that, a radical function is defined for only non negative radicand.

In option A, the function is defined if

$x+11\geq 0$

$x\geq -11$

The domain of this function is $x\geq -11$. So, option A is correct.

In option B, the function is defined if

$x-11\geq 0$

$x\geq 11$

The domain of this function is $x\geq 11$. So, option B is incorrect.

In option C and D, the function is defined if

$x+5\geq 0$

$x\geq -5$

The domains of these function are $x\geq -5$. So, options C and D are incorrect.

Hence, option A is correct.
