The function f(x) = 0.4x2 – 36x + 1000 models the number
of accidents, f(x), per 50 million miles driven as a function of
a driver's age, x, in years, for drivers from ages 16 through 74,
inclusive. The graph of f is shown. Use the equation for f to solve
Exercises 45–48.

Age of Driver
45. Find and interpret f(20). Identify this information as a
point on the graph of f.
46. Find and interpret f(50). Identify this information as a
point on the graph of f.
47. For what value of x does the graph reach its lowest point?
Use the equation for f to find the minimum value of y.
Describe the practical significance of this minimum value.
48. Use the graph to identify two different ages for which drivers
have the same number of accidents. Use the equation for f
to find the number of accidents for drivers at each of these
ages.

The January readings for various years are shown in Figure . In the July 1990 issue of Scientific American, these data were used to predict the carbon dioxide level in Earth’s atmosphere in the year 2035, using the quadratic model y = 0.018t2 + 0.70t + 316.2 (Quadratic model for 1960–1990 data) where t = 0 represents 1960, as shown in Figure a. The data shown in figure b represent the years 1980 through 2014 and can be modeled by y = 0.014t2 + 0.66t + 320.3 (Quadratic model for 1980–2014) data where t = 0 represents 1960. What was the prediction given in the Scientific American article in 1990? Given the second model for 1980 through 2014, does this prediction for the year 2035 seem accurate?arrow_forward
