The Yukon Quest is an animal dogsled race between Whitehorse, YT and Fairbanks, Alaska. The race distance is
1645 km. Racers must have between 8 and 14 dogs for
this challenging race. Many racers have built kennels
to transport the dogs to the race. One competitor
has built a trailer that is a right rectangular
prism measuring 2 m wide by 1.6 m high by
3.2 m long. He has divided this trailer into
16 identical kennels for his dog team, as
shown in the diagram. How much material
is needed to build the kennels?

by definition, an arc subtended by a central angle of some given measure has the same measure. so .

step-by-step explanation:

given the function as;

write the equation replacing f(x) with y

form   and fill a table containing values of y with corresponding values of x

you can take a range for   values of x as -3≤x≤3

solving for x=-3

for x=-2

repeat the same procedure to get the values of y for the remaining ,x=-1 to x=3

plot the values of y against values   of x and obtain the following graph
