At the start of 2010, an online social group had 360 million members. Subsequently, new members joined at a rate of roughly m(t) = -6.6t2 + 12t + 260 million members per year (0 sts 5), where t is time in years since the start of 2010. (a) Find an expression for the total online social group membership M(t) at time t. HINT [See Example 6.] M(t) = (b) Use the answer to part (a) to estimate the online social group membership midway through 2014. (Round your answer to the nearest 1 million members.) M(4.5) = million members
