A = {multiples of 3 between 20 and 32} B = {odd numbers between 20 and 32}
C = {even numbers between 20 and 32}
a) List the members of A U B​

A={21,24,27,30}

B={21,27}

C={24,30}

Step-by-step explanation:

a)A U B={21,24,27,30}

b)A n C ={24,30}

9514 1404 393

  A ∪ B = {21, 23, 24, 25, 27, 29, 30, 31}

  A ∩ C = {24, 30}

Step-by-step explanation:

  A = {21, 24, 27, 30} . . . . . . . . . . . . . multiples of 3

  B = {21, 23, 25, 27, 29, 31} . . . . . . . odd numbers

  C = {20, 22, 24, 26, 28, 30, 32} . . . even numbers

The union is the list of numbers in either set.

  A ∪ B = {21, 23, 24, 25, 27, 29, 30, 31}

The intersection is the list of numbers in both sets.

  A ∩ C = {24, 30}

c

step-by-step explanation:

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.
