The coordinates of point $H$ on the graph are $(1997, 176.98)\text{.}$ What do the coordinates tell you about the function $f\text{?}$
$f(1997) = 176.98$ ; the average water level was 176.98 meters in 1997.
$f(176.98) = 176.98$ ; the average water level was 176.98 meters in 1997.

The average water level in $2004$ was $176.11$ meters. Write this fact in function notation. What can you say about the graph of $f\text{?}$
$f(176.11) = 2004$ . The point $(176.11, 2004)$ lies on the graph of $f$ .
$f(2004) = 176.11$ . The point $(2004, 176.11)$ lies on the graph of $f$ .
