Answer:

\{(2,8),(2,1),(-9,-5),(-8,9)\} is not a function

Step-by-step explanation:

Given

\{(-3,-1),(8,-1),(0,-5),(-9,-2)\}

\{(5,9),(-3,-5),(0,4),(-9,9)\}

\{(9,0),(-5,4),(5,0),(6,3)\}

\{(2,8),(2,1),(-9,-5),(-8,9)\}

Required

Which is not a function

A function is of the form (x,y)

Assume a function is:

\{(x_1,y_1),(x_2,y_2),(x_3,y_3).....,(x_n,y_n)\}

In simple terms:

For an ordered pair to be regarded as a function, no x value must be repeated

Analyzing the options:

1. \{(-3,-1),(8,-1),(0,-5),(-9,-2)\}

This is a function because none of the x values (-3, 8, 0 and -9) appeared more than once

2. \{(5,9),(-3,-5),(0,4),(-9,9)\}

This is a function because none of the x values (5, -3, 0 and -9) appeared more than once

3. \{(9,0),(-5,4),(5,0),(6,3)\}

This is a function because none of the x values (9, -5, 5 and 6) appeared more than once

4. \{(2,8),(2,1),(-9,-5),(-8,9)\}

This is not a function because one of the x values (2) appeared more than once.

i.e.

(2,8)   and   (2,1)

Divisibility rules for 2, 5, and 10
Simora [160]

Answer:

none of these

Step-by-step explanation:

A number is divisible by 10 if the last digit of the number is 0. The numbers 20, 40, 50, 170, and 990 are all divisible by 10 because their last digit is zero, 0.

In proper paragraph form,explain the difference between the union and intersection of two sets.
Sophie [7]

The <em><u>correct answer</u></em> is:

The union of two sets is a combination of all elements from both sets.  The intersection of two sets, on the other hand, is a set of the elements common to both sets.

For instance, if we have the sets {1, 3, 5, 7, 9} and {3, 6, 9, 12, 15}, the union would be the combination of both:

{1, 3, 5, 6, 7, 9, 12, 15}

The intersection of the sets would be the common elements.  The only elements that are in both sets are 3 and 9.  This makes the intersection

{3, 9}
