The Answer of The result of a quadratic model fit to time-series data was $ = 8.5 - 0.25 t + 2.5 t ^ { 2 }$ , where t = 1 for 1994. The forecast value for 2001 is 129.25.

The Result of a Quadratic Model Fit to Time-Series Data =8.5−0.25t+2.5t2 = 8.5 - 0.25 t + 2.5 t ^ { 2 }=8.5−0.25t+2.5t2

The Result of a Quadratic Model Fit to Time-Series Data $= 8.5 - 0.25 t + 2.5 t ^ { 2 }$
