If a customer bought an item that had a full price of $525 from a retailer, how much in total will the retailer receive in the end if the customer used a coupon for $75?

  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.
