Question

Determine which ordered pair is a solution of y = x^2– 2.
A. (–2, 6)
B. (5, 21)
C. (–1, –1)
D. (–5, 24)

Answer 1

Plug in each ordered pair into the equation and see which ones hold true. For example with an ordered pair like \((1, 0)\), we'd plug it into \(y = x^2-2\) like so: \[
(1) = (0)^2 -2 \\
1 = 0-2 \\
1 = -1
\]Since it's obvious that \(1 \neq -1\), the ordered pari \((1, 0)\) is not a solution.

Answer 2

The answer is C (-1,-1).
