Problem 151 of 7
Choose a reasonable model type for scatter-plot data described by points initially rise, then fall, forming a single peak.
Using a hint is okay. It just tells the trainer to give you a little more review.
Hidden until you reveal it.
match data form to linear, exponential, or quadratic model.
Hidden until you reveal it.
Scatter description must reveal form well enough to choose linear, exponential, quadratic, or no simple model.
Enter your answer
Your answer is equivalent to the expected form.
Walkthrough
Full solution stays hidden until you ask for it.
1. Identify the overall form of the point cloud.
2. Match straight trends to linear, multiplicative curves to exponential, and one-turning-point curves to quadratic.
3. Choose no simple model if no pattern is visible.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
Choosing based only on direction when form is nonlinear.
