4. The bus and the train left the same town headed south at 8 a. m. At noon, the bus was 100 miles behind the train. How far did each one travel if the speed of the train was twice the

speed of the bus?

see attached

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

combine all like terms then its just a 2 step equation
