N=0.05t^2-0.42t+12.33
Here N is trhe enrollment in millions of students , t is the time in hyears since 1986, an the moder is relevant form 1986 to 1996.
Use functinal notation to express teh nuber of students enrolled in U.S. scholls in 1991
So here, t must be 5 and we have:
N=0.05(5)^2-0.42(5)+12.33 = 11.48M = 11, 480,000
