Sunrise Sky Spa creates a function to model their memberships over the years since 2000. This graph shows a function of the number of memberships at Sunrise Spa, M(t), where t is the number of years since 2000. [The graph has number of years since 2000 plotted on the x axis and number of memberships in thousands plotted on the y axis and shows a curve that begins at (0, 12), falls slightly, rises with decreasing steepness, and then rises with increasing steepness. The curve continues to rises with decreasing steepness to the point, labeled C, then falls with increasing steepness through the point, labeled, F, and rises again.] 2018 WGU, Powered by GeoGebra Question 10 of 12 Question 10This is not a form; we suggest that you use the browse mode and read all parts of the question carefully. When the number of memberships is decreasing, would management prefer the function be concave-up or concave-down? Management would rather see a concave-down curve because the memberships would decrease more and more slowly. Management would rather see a concave-down curve because the memberships would decrease faster and faster. Management would rather see a concave-up curve because the memberships would decrease more and more slowly. Management would rather see a concave-up curve because the memberships would decrease faster and faster
