The graph of h represents the distance (measured in feet) of a gopher from its home as a function of the time (number of seconds) since the gopher left his house. Over what approximate time interval(s) does the gopher\'s distance from home decrease? From 4.1 to 12.1 seconds only From 12. 1 to 17 seconds only From 4.1 to 12.1 seconds and from 17 to 19 seconds From 0 to 8 seconds and from 15 to 19 seconds None of the above

Solution

From the graph,we can say that the graph is decreasing in the time interval 4.1 to 12.1 seconds and 17 to 19 seconds.

Therefore the gopher\'s distance from home decrease in the time interval 4.1 to 12.1 seconds and from 17 to 19 seconds.
