What is the median for the following set of data? 5, 7, 8, 10, 12, 12

12
10
9
7

9

The middle numbers are 8 and 10. 9 is the number in between them which means it is the median.

  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.
