lets check 0,4 put in 0 for x
4*0+4 =4 good
4 * 2^0 =4 good
4*0+8 =8 no good
(0+2) ^2 =4 good
for the next point we only need to check 3 functions
(1,8)
4*1+4 =8 good
4 * 2^1 =*8 good
4x+8 don't care since it didn't work for (0,4)
(1+2) ^2=8 good
for the next point we need to check 3 functions
(2,12)
4*2+4 =12 good
4 * 2^2 =16 no good
4x+8 don't care since it didn't work for (0,4)
(2+2) ^2=16 no good
Choice A
