For each of the following fitted trends, make a prediction for period t = 17:

(a )y_t = 2,286e^0.076t(Do not round the intermediate calculations. Round your final answer to 1 decimal place.)

y =

(b)y_t = 1,149 + 12.78t(Do not round the intermediate calculations. Round your final answer to 1 decimal place.)

y =

(c)y_t = 501 + 18.2t - 7.1t²(A negative value should be indicated by a minus sign. Do not round the intermediate calculations. Round your final answer to 1 decimal place.)

y=
