The math club is doing a fundraiser to raise money for to attend a math competition. the club was told by their advisor to raise $2000, but they decided to raise $4000. the club is selling" i like tt" t shirts for $10 and sweatshirt for $20 let x equal the number of t shirt sold and let y equal the number of sweatshirt sold

  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.
