PLEASE HELP! By visual inspection, determine the best-fitting regression model for the data plot below.
2 answers:
The initial step is to analyze the graph's behavior.
It doesn’t follow a linear pattern, as the rate of change is inconsistent.
It also isn’t exponential since the change rate doesn't fluctuate significantly.
For this scenario, the most suitable regression model would be of the type:
Where,
a <0: This indicates that the parabola opens downwards.
Hence, the most appropriate regression model is quadratic.
Answer:
From visual analysis, the most fitting regression model for the data observed is:
A. Quadratic

Answer: Option C is the correct graph.
Explanation:
An odd function satisfies the condition,
This indicates that for any point (x,y) on the graph, the point (-x,-y) will also be present.
Why Option C is correct:
Option C includes the point (1,2), which implies the point (-1,-2) must be present.
Indeed, (-1,-2) is among the points.
Other pairs like (2,3) with (-2,-3), (3,-1) with (-3,1), and (4,0) with (-4,0) are also found. Hence, the function represented is odd.
Why other options are incorrect:
In Option A, (1,3) is given, so at x = -1, y should be -3, but instead y = 1, so it’s not odd.
Option B has (1,0), so at x = -1, y should be 0, but y = -3, so it is not odd.
Option D features (1,-1), meaning at x = -1 y should be 1; however, y = -1, so it's not odd.
