Activity 2 Function Notation Data indicate that U.S. women are delaying having children longer than their counterparts 50 years ago. The table shows P f(t), the percent of 20-24 year old women in year t who had not yet had children. (Source: U.S. Dept of Health and Human Services) 1960 1965 1970 1975 1980 1985 1990 1995 2000 Year, t % of Women, P 47.5 51.4 47.0 62.5 66.2 67.7 68.3 65.5 66.0 a. How does the table support the assumption that P is a function of t? Does this assumption make sense for the context of the problem?
