A local chapter of a bicycling organization began its membership in 1985. The number of chapter members in any given year is given by the equation below, where t is equal to the number of years after 1985. A graph is created to show the membership growth over the last several years. M(t) = 50 + 125t If the graph continues forever, which of the following describes the end behavior of the graph? A. As t approaches positive infinity, M(t) remains constant. B. As t approaches positive infinity, M(t) approaches positive infinity. C. As t approaches positive infinity, M(t) approaches negative infinity. D. As t approaches positive infinity, M(t) approaches zero.
