find seven ordered pairs to the equation y= x^2-3
$$y=x^2-3\\\\ \begin {tabular}{|c|c|c|c|c|c|c|c|}\hline $x$&\;\;-1\;\;&\;\;0\;\;&\;\;1\;\;&\;\;2\;\;&\;\;3\;\;&\;\;4\;\;&\;\;5\;\;& \hline $y$&(-1)^2-3=-2&0^2-3=-3&1^2-3=-2&2^2-3=1&3^2-3=6&4^2-3=13&5^2-3=22& \hline \end{tabular}$$
Do you mean ordered pairs like cartesian coordinates (x,y)?
If so:
y = x^2 - 3
1. (1,-2)
2. (2, 1)
3. (3, 6)
4. (4, 13)
5. (5, 22)
6. (-1, -2)
7. (-2, 1)
