$f( - 4) = 4( - 4) + 9 = - 7$

_________________________________

$f( - 2) = 4( - 2) + 9 = 1$

$f(0) = 4(0) + 9 = 9$

_________________________________

$f(2) = 4(2) + 9 = 17$

Thus ;

R = { - 7 , 1 , 9 , 17 }

qwelly [4]

Because there are only two things you can do with these two " family" members. 81 divided by 9 is 9. 9 times 9 is 81. Strictly speaking, there should be three in the family: 9,9 and 81 9 is the square root of 81. 81 is the 9 squared.
