Answer:
2.85 x 10^4
Step-by-step explanation:
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

5
6(5)-5^2
30-25

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
