There are 1 4/9 times as many white as black notes on a full sized piano keyboard. There are 88 notes altogether. Determine the number of white notes and the number of black notes.

  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.

step-by-step explanation:

the true ones are a b and d
