Question 1156646: Solve. Use a graphing calculator if necessary. See Examples 9 - 11. (Objective 8)
The total annual enrollment (in millions) in a country's elementary and secondary schools for the years 1975 - 1996 is given by the function
E(x) = 0.056x2 − 1.154x + 50.604.
For this period, what was the lowest enrollment? (Round your answer to one decimal place.)
The lowest enrollment was about-
million.

This is a quadratic and has a minimum
the x value is at -b/2a or 1.154/0.112=10.30 years
y=44.659 or 44.7 million, substituting the value of x into the equation. Use a graphing calculator and round at the end, not in between.
