Answer:
1999
Step-by-step explanation:
y  = 0.2313(y - 1992)^2 + 2.600(y - 1992) + 35.17
verify with known data point
y  = 0.2313(2004 - 1992)^2 + 2.600(2004 - 1992) + 35.17
y  = 0.2313(12)^2 + 2.600(12) + 35.17
y  = 27.9873 + 28.6 + 35.17
y = 99.6772  which verifies our equation
65 = 0.2313x² + 2.6x + 35.17 
  0 = 0.2313x² + 2.6x - 29.83
quadratic formula
x = (-2.6 ±√(2.6² - 4(0.2313)(-29.83))) / (2(0.2313))
x = (-2.6 + 5.86) / 0.4626 = 7.05 years
7.05 = y - 1992
y = 1999.05
