Ответ:
Set the radicand (stuff under the radical) greater than or equal to 0. Solve x+11 >= 0 for x to get x >= -11
Ответ:
we proceed to resolve each case to determine the solution
we know that
The radicand is a number or quantity from which a root is to be extracted
In this problem the radicand must be greater than or equal to zero
case A
the radicand is equal to
so
the domain is the interval--------> [-11.∞)
therefore
the function is the solution of the problem
case B
the radicand is equal to
so
the domain is the interval--------> [11.∞)
therefore
the function is not the solution of the problem
case C
the radicand is equal to
so
the domain is the interval--------> [-5.∞)
therefore
the function is not the solution of the problem
case D
the radicand is equal to
so
the domain is the interval--------> [-5.∞)
therefore
the function is not the solution of the problem
the answer is the function
