Visas The number of skilled workers’ visas issued in the United States can be modeled by y = −1.48x2 + 38.901x − 118.429, where x is the number of years after 1990 and y is the number of visas in thousands.
a. Use numerical methods to determine the year when the number of visas issued was a maximum.
b. What was the maximum number of visas issued?
c. During what year after 2000 does the model indicate that the number of visas issued would be 100 thousand?
