Answer
The graph of the function h=6-0.3j is a discrete graph because the graph has a domain of 0-20 ounces.
The graph of the function is shown below.
Work Step by Step
The graph of the function h=6-0.3j is a discrete graph because the bottle has a maximum of 20 ounces and minimum of 0 ounces. The graph is discrete because after drinking 20 ounces, the height of juice is 0 inches and therefore the bottle cannot have negative height. Thus it is a discrete graph because the height changes after drinking specific ounces of juice.
In addition, the domain is from 0 to 20 ounces because the bottle can have a max height of h=6-0.3(0)=6 inches when you drink 0 ounces of juice and max height of 0 inches, when you drink 20 ounces of juice.
