the height of a model rocket in feet h(t) as a function of time t in seconds is shown in the graph.
what is the practical range for the function h(t)?
[0,64]
[0,4]
all positive integers
all real numbers
The range consists of the set of all possible heights.....this is any height between 0 and 64, inclusive
So
[ 0, 64 ]
