13) Solve the inequality algebraically: State the solution(s) using inequality(ies) -3x^2 > 0.
Use the following information for 14: A snowstorm begins at 10 am. It begins as light snowfall, builds up to heavy snowfall, and then drops back to light snowfall and stops. The rate (in inches per hour) at which snow is falling is given by the function s(t) below, where t is the time (in hours) since the snowstorm began:
s(t) = 0.5t^2 + 2.75.
14) Graph the function.
b) For how long does it snow, in hours?
c) When during the snowstorm is the rate increasing? Give your answer as an inequality.
