Which is the better buy? brand a which is sold as a 1-gallon can of paint for $13.99 or brand b which is 5-gallon bucket of paint for $67.45. determine the cost per gallon for each brand of paint and state which is the better buy.

  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.
