Use pemdas ( 12 - 3)^2 - ( 14/2)

Step-by-step explanation:

you start with the fist set of parenthesis ,you start inside with which eaquals 9, than you square 9= . than you go to the second set of parenthesis . than you subtract 7 from 81 =

  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.
