A tank is being filled with a liquid. L (t), given below, is the amount of liquid in liters in the tank after t minutes. L (t) = 2.5t+ 11.5 Complete the following statements. Let L'be the inverse function of L. Take x to be an output of the function L. log Olog That is, x = L (t) and t = _-(x). (a) Which statement best describes _(x)? No solution 0=0 O The reciprocal of the amount of liquid (in liters) after x minutes. X 5 ? O The amount of time (in minutes) it takes to have x liters of liquid. O The amount of liquid (in liters) after x minutes. O The ratio of the amount of liquid (in liters) to the number of minutes, x. ( b ) I ( x ) = 0 (C) I(90 ) = 0
