Question

Graph the relation {(5, 0), (0, 5), (5, 1), (1, 5)}. Is it a function? Why or why not?

Answer 1

A. Yes, it passes the horizontal-line test
B. Yes, it passes the vertical-line test.
C. No, it does not pass the vertical-line test..
D. No, it does not pass the horizontal-line test

these are my choices

Answer 2

\(\bf {(5, 0), (0, 5), (5, 1), (1, 5)}\implies
\begin{array}{llll}
x&\bf y\\
\hline\\
5&0\\
0&5\\
5&1\\
1&5
\end{array}\)

recall, to pass the vertical line test, or be a function
each "y" must have a unique "x" in the set
