THE FUNCTION D(X) MODELS THE CUMULATIVE NUMBER OF DEATHS FROM A DISEASE X YEARS AFTER 1984. ESTIMATE THE YEAR WHEN THERE WERE 90,000 DEATHS
D(x)=2010X^2+5400X+5774
D(x)=2010X^2+5400X+5774

Well, we could solve the quadratic but it says estimate.
make a guess at say ten years
d(10) = 201,000 + 54,000 + 5,774 way too big
d(5) = 50,250 + 27,000 + 5774 = 83,024
d(6) = 110,534
so between five and six years after 1984
So 1989
