Solve the problem.The percent increase for in-state tuition at a certain public university during the years 1991 through 1999 can be modeled by the quadratic function defined by f(x) = 0.151x2 - 2.05x + 10.9, where x = 1 represents 1991, x = 2 represents 1992, and so on.(i) Based on this model, by what percent (to the nearest tenth) did tuition increase in 1991?(ii) In what year was the minimum tuition increase? (Round down to the nearest year.) To the nearest tenth, by what percent did tuition increase that year?
A. (i) 7.4%; (ii) 1995; 4.4% B. (i) 18.4%; (ii) 1998; 37% C. (i) 10.9%; (ii) 1996; 4% D. (i) 9%; (ii) 1997; 3.9%
