Answer
Appendix C – 15 (Answer)
Refer to the line y = –x + 2 in Graph I, it is a function because
one value of y can always be found by adding 2 to each value of –x, so,
x can be represented by any real number with domain = $(-\infty, \infty)$, and
y can be any real number with range = $(-\infty, \infty)$.
