For each of the following fitted trends, make a prediction for period t = 17: (a) yt = 2,286e0.076t (Do not round the intermediate calculations. Round your final answer to 1 decimal place.) yˆy^ = (b) yt = 1,149 + 12.78t (Do not round the intermediate calculations. Round your final answer to 1 decimal place.) yˆy^ = (c) yt = 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.) yˆy^ =
Equations and Inequations
Equations and inequalities describe the relationship between two mathematical expressions.
Linear Functions
A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.
