Question: Prevalence of alzheimer's patients based on a study conducted in 1997, the percent of the u.s. Population by age afflicted with alzheimer's disease is given by the function

P(x) = 0.0726x2 + 0.7902x + 4.9623               (0 ≤ x ≤ 25)

Where x is measured in years, with x = 0 corresponding to age 65 yr. Show that p is an increasing function of x on the interval (0, 25). What does your result tell you about the relationship between alzheimer's disease and age for the population that is age 65 yr and older?
