Which graph could represent the data shown below?

Answer 1

From the attached diagram you can see that regression that best fits given data is quadratic (not linear).

• option 2 is true, it gives graph, similar to quadratic parabola;
• options 3 and 4 are false, because graphs are decreasing.

Answer: correct choice is B.
