Is this an appropriate prediction? Yes, this is an appropriate extrapolation since you can extrapolate out as far as 6+0.75(5) = 6 +3.75 = 9.75. Yes, this is an appropriate extrapolation since you can extrapolate out as far as 6 + 5 = 11. O No, this is an extreme extrapolation since the largest extrapolation value that should be attempted here is 6+0.25(5) 6+1.25 = 7.25. O No, this is an extreme extrapolation since the largest extrapolation value that should be attempted here is 6+0.5(5) = 6+2.5 = 8.5.
