Bettina spent $75 on 5 shirts that each cost the same price. three of the shirts were red. which expression represents the total cost of the red shirts? a. 75 × 3/5 b. 75×5/3 c. 75/5 ×1/3 d. 75/3 × 1/5 plz

  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.
