math 1:
suppose that the function f(x) = 2x + 12 represents the cost to rent x video games a month from an internet gaming club. george now has $4. how many more dollars does george need to rent 13 video games next month?

  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.
