Answer:
B. Quadratic
Explanation:
We are given the scatter plot representing a data.
Now, it is required to find the best regression model for the scatter plot.
From the graph, we see that,
The scatter plot has a behavior similar to a quadratic equation.
That is, the graph is starting and ending in the same direction.
Also, the points in the scatter plot are increasing at first to reach a maximum value and then decreasing.
Thus, we have that,
Visually the scatter plot represents a quadratic equation.
So, option B is correct.
