Questions? 1. An article in the Washington Post concerned a surgical procedure called radial keratotomy (RK), which reduces or cures nearsightedness. According to the 1994 article, the number of patients who have had this surgery each year has grown exponentially in the last 5 years. (This is of course the same as saying that the number of patients is following a geometric growth pattern.) The article reported that 30,000 RK surgeries were performed in 1993 and that 250,000 would be performed in 1994. a) Find a difference equation and a functional equation to model this growth pattern. Ratio r= 250000/30,000= 8.333 s Diff. ns Roti = (8.333)Rn, Ro = 30,000 n=years after 1993. Functional Equation: R(n) = 30,000(8.333)"
