Sharon was going through the financial records of her company. the profit earned by the company, p(t), over time t, in years, for five consecutive years can be modeled by a quartic function. each of the following functions is a different form of the quartic model for the situation given above. which form would be most if attempting to determine the time at the which the company did not earn any profit? a. p(t) = 40(t - 3)(t + 2)(t - 5)(t + 3) b. p(t) = 40(t2 - t - 6)(t2 - 2t - 15) c. p(t) = 40t(t3 - 3t2 - 19t + 27) + 3,600 d. p(t) = 40t4 - 120t3 - 760t2 + 1,080t + 3,600
