The rate of change of the percent of obese Americans who are severely obese can be modeled by the function percentage points per year, where x is the number of years after 1980.

(a) If 8.3% of obese Americans were severely obese in 1995, find the function f(x) that gives the percent of obese Americans who are severely obese. Use three significant digits.
(b) Use the function from part (a) to predict the percent of obese American adults who will be severely obese in 2025.
