1. Which type of regression is most appropriate for data that shows a constant rate of change?

Quadratic

Exponential

Linear

Logarithmic

2. The is a measure of how well a regression model fits the observed data.

3. When data points form a parabolic shape, a regression is typically the best fit.

4. Explain the difference between interpolation and extrapolation when using a curve of best fit.

5. Describe a real-world scenario where an exponential curve of best fit would be appropriate.
