ANSWER WITH SOLUTIONS

"The life expectancy for females born during 1980-1985 was approximately 77.6 years. This grew to 78 years during 1985-1990 and to 78.6 years during 1990-1995. Construct a model for this data by finding a quadratic function whose graph passes through the points (0,77.6), (5,78), and (10,78.6). Use this model to estimate the life expectancy for females born between 1995 and 2000 and for those born between 2000 and 2005."
