Which function has the domain x> =-11

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

b) well because you get well

the answer would be 1 1/72

step-by-step explanation:

you can rewrite the equation by separating the parts and then solving individually:

10-9=1

1/8 - 1/9=

find l c d and then combine:

1 1/72
