23. To allow enough distance for cars to pass on two-lane highways, engineers calculate minimum sight
distances between curves and hills. The table shows the minimum sight distance y in feet for a car traveling at
x miles per hour.
x (in mph) 20 30 40 50 60 65 70
Y (in feet) 810 1090 1480 1840 2140 2310 2490
a) Determine the best-fitting model to represent this data. Determine whether a linear or cubic model is the
best fit. Write the model.
b) Estimate the sight distance for a car traveling 43 mph.
