Assuming that x2=x^2 or x squared so evaluate basically subsitute values for x
0 6(0)-0^2 0-0 0
1 6(1)-1^2 6-1 5
2 6(2)-2^2 12-4 8
3 6(3)-3^2 18-9 9
4 6(4)-4^2 24-16 8
5 6(5)-5^2 30-25 5
6 6(6)-6^2 36-36 0
if we were to display the results on a table with the numbers we subsituted on the left and results on the right we would get 0,0 <span>1,5 </span>2,8 <span>3,9 </span><span>4,8 </span><span>5,5 </span>6,0
we notice that the outputs/results go up then down the outputs were 0,5,8,9,8,5,0 when the inputs were 0,1,2,3,4,5,6
Lets start with 416 First go to the 6 and since its over 4 we can automatically know that it makes the 1 in 416 to a 2 and the 2 cannot go up any higher so we make everything else below 4 a zero.
