A giant candy bar costs C dollars last week. This week the price doubled. How much would you pay today if you wanted 3 giant candy bars, and also had a $2 coupon off the total cost? Write this as an expression in terms of C. ​

((c*2)3)-2=x

x = total cost

  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.
