Acar travels at a constant speed. what is the car's speed between checkpoints, expressed as a unit rate
check point a 1: 00 120 miles
check point b 3: 00 208 miles

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
