Section 2.6 Practice - Analyzing Real-World Functions

Let the graph represent the relation H(t) where H represents the height of a diver jumping off of a diving board at any given time t. The height was measured in feet and the time was measured in seconds.

What/where is the domain AND what does it mean in this context?

• $0\le t\le28$

• $-12\le H\left(t\right)\le18$

• The diver was diving between 0 and 28 seconds

• The diver's height above the water was between -12 feet and 18 feet during the dive.
