The first thing you should do is observe the behavior of the graph.
 It is not linear because the rate of change is not constant.
 It is not exponential because the rate of change does not grow or decrease rapidly.
 For this case the best regression model is a model of the form:
 y = ax ^ 2 + bx + c

 Where,
 a <0: This is because we have a parabola that opens downwards.
 Therefore, the best regression model is quadratic.
 Answer:
 
By visual inspection, the best-fitting regression model for the data plot is:
 
A. Quadratic

Madison buys supplies so she can make and sell wind chimes. She begins
Studentka2010 [4]
<h3>Explanation:</h3>

In the graph x-coordinate represents the number of wind chimes sold and y-coordinate represents the profit Madison earned. If a point is below the x-axis, means it has negative y-coordinate than it represents loss. Points above x-axis should have x-coordinate more than 6 as stated in the question that she started earning profit after selling her first 6 wind chimes. All the points having x-coordinate less than 6 should lie on or below the x-axis.

By the above statement point B is completely wrong. Point C and Point A are also wrong as they both x-coordinate more than 6 but still they are below x-axis.

Point D is the makes most sense here as it has x-coordinate more than 6 and it is above x-axis. This means that when Madison sold 7 wind chimes she was in a profit of $3.75.
