a number of two digits in such that four times the unit digit is greater than thrice the tens digits, when the digits are reversed the number is increased by 9. find the number​

  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.

answer: 1+1

step-by-step explanation: 1+1 is at least 2
