Can you predict the life expectancy for an individual born in
the United States in certain years?
Year of Birth: 1950; 1965; 1973; 1982; 1987; 1992; 2010;
2015
Life Expectancy: 70.2; 69.3; 71.4; 74.5; 75; 75.7; 78.7,
79.2
If you can make predictions, when year of birth is 1990, what
is the life expectancy? Please answer in a whole number.
If you can’t make a prediction, put the word "none" in the
answer box.

The life expectancy for females in a certain country born during
1980−1985 was approximately 75.2 years. This grew to 76 years
during 1985−1990 and to 76.2 years during 1990−1995. Construct a
model for this data by finding a quadratic equation whose graph
passes through the points (0,75.2),(5,76),and (10,76.2).
Use this model to estimate the life expectancy for females born
between 1995 and 2000 and for those born between 2000 and 2005.
Let x be the number of years since 1980...
