Can someone answer “a” for me?

Answer:
Step-by-step explanation:
Start your table by typing "s" and "A = s^2" as headers.
We're told not to exceed s = 5 units. And s cannot be negative, as all length measurements are positive or zero.
Thus, if s = 0, A = (0)^2 = 0 and you have the point (0,0).
If s = 1, A = (1)^2 = 1 and you now have the point (1,1) in the second row of your table.
If s = 2, A = (2)^2 = 4 => (2,4)
and so on:
s A = s^2
0 0
1 1
2 4
3 9
Keep going until you've finished with s = 5 units.
