Which of the following sets are closed under division? select all that apply. integers irrational numbers whole numbers polynomials none of the above

None of the Above

Step-by-step explanation:

Integers:

Take

Here,

Since is not an integer , integers are not closed under division .

Irrational Numbers:

Take

Here,

Since is not an irrational number , irrational numbers are not closed under division.

Whole Numbers:

Take

Here,

Since is not a whole number, whole numbers are not closed under division.

Polynomials:

Take two polynomials as

Here, is not defined.

Since is not a polynomial, polynomials are not closed under division .

So, the correct option is none of the above

the formula of a slope:

from a table we have

substitute:

the slope of f(x) is -1.

the graph of funcfion g(x) is a horizontal line. the slope of a horizontal line is equal 0. therefore the slope of g(x) is 0.

-1 < 0
