Question
Use exponential regression to fit the following data set. (Round your answers to two decimal places.)
| x | 4 | 11 | 15 | 17 | 18 |
|---|---|---|---|---|---|
| y | 1.0 | 17.3 | 87.6 | 197.1 | 295.6 |
Give the exponential model.
y = 0.24 × 1.80x
y = 0.28 × 1.05x
y = 0.20 × 1.50x
y = 0.14 × 2.10x
y = 0.18 × 0.90x
Use the model found above to calculate y(8).
y(8) =
Solve y = 177 for x.
