Two years ago a father was four times as old as his son. three years from now the father will be only three times as old as the son. how old is each now?

if x represents the son's age two years ago, which expression represents his father's age three years from now?

3x + 15

Step-by-step explanation:

The expression would be 3x + 15 I just did this one ;)

56

step-by-step explanation:

  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.
