The formula y=2.9√x+8ymodels the percent of U.S. adults who are considered obese by federal guidelines, where xx is the number of years after 1988, and yy is the percent of obese adults. In this equation, yy is already converted from a decimal, so, for example, a 55% obesity rate would correspond to y=55. According to this formula, in what year was the obesity rate 15.1 percent? Answer: In the year

Linear Functions
A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.
