Given a = {x | x < 1}, b = {x | x ≥ 5}, and c = {x | x = 5}, match the following items.
1.a∪b ( ){x | x = 5}
2.a∪c ( ){x | x < 1 or x = 5}
3.b∪c ( ) {x | x < 1 or x ≥ 5}
4.a∩b ( ) ø
5.b∩c ( ){x | x ≥ 5}

  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.

i did it myself and i got 4.2 (b) hope its right

step-by-step explanation:

use distributive property on all like terms and change your signs if you have a double negative or if you have positive/negative
