The field inside a running track is made up of a rectangle that is 84.39 m long and 73 m wide, together with a half-circle at each end.
9.76m
73m
73m
84.39m

The track is 9.76 m wide all the way around. What is the distance around the
outside of the track?

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

this would be 35. 35 + 5 = 40. you take the known constant and subtract by the answer of the equation and you get y.
