Loretta is trying to build the largest taco in the world . she use 2000 pound of ground beef one tenth as many pound of cheese as beef and one hundred as many pound of lettuce as beef. how many pound of lettuce and cheese combined did she use

  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.
