between 1998 and 2004, the number of college freshman who planned to get a professional degree computer science can be reasonably modeled by
f(x)=348.2x^2+1402x+13,679
where x=0 represenjts 1998. based on this model, in what year did the percent of freshman planning to get a computer degree reach its maximum?

for y = ax^2 + bx + c, the max or min is reached at x = b/2a = 1402/696.4
