Jose’s credit card statement says that he owes $324.he charges an additional $63,$21,and $75. how much does he owe now

  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.

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value
