Answer

Explanation:

Step1: Analyze exponential - model suitability

Exponential models have a characteristic curved - growth or decay pattern. In scatter plots, if the data points show a rapid increase or decrease in a non - linear, curved fashion, an exponential model may be appropriate. For the scatter plots in question 1, visual inspection is needed. But generally, if the points seem to follow a curve that gets steeper or shallower in a non - linear way, the answer is yes; if they seem to follow a straight - line or a different pattern, the answer is no.

Step2: Evaluate investment models

For the investment problem in question 2, linear regression has a constant rate of change (a straight - line). Quadratic regression has a parabolic shape. Exponential regression has a rapid growth rate over time. In real - world investment scenarios where the value can grow at an increasing rate over time, an exponential model is often more suitable as it can capture compounding effects.

Answer:

  1. (Answers depend on visual inspection of scatter plots. Without seeing the actual plots clearly, we can't give definite yes/no answers)
  2. Exponential Regression Model
