From 1959 to 2019, the number of students S (in thousands) enrolled in United States public schools can be modeled by the function below where x is the number of years since 1959.
S(x)=1.94x^3-142x^2+1910x+79580
1. Graph the function. Label axes and provide a title.
2. Identify any turning points on the domain 0 < x < 60. What real-life meaning do these points have?
3. What is the range of the function for the domain 0 < x < 60? What real-life meaning do these points have?
