Easy Math · Problem-Solving and Data Analysis · Two-variable data: Models and scatterplots · MCQ

The figure presents a scatterplot in the x y plane. The numbers 0 through 6, in increments of 1, are indicated on the x axis. The numbers 0 through 20, in increments of 2, are indicated on the y axis. There are 12 data points in the scatterplot. The data points are in the shape of a parabola that opens upward. The data points begin on the y axis at 20, and trend downward and to the right until they reach a first low point with coordinates 2 point 5 comma 5 and a second low point with coordinates 3 comma 5. Then the data points trend upward and to the right until they reach the last point with coordinates 5 point 5 comma 20.

Of the following, which is the best model for the data in the scatterplot?

A
$y equals, 2 x squared, minus 11 x, minus 20$
B
$y equals, 2 x squared, minus 11 x, plus 20$
C
$y equals, 2 x squared, minus 5 x, minus 3$
D
$y equals, 2 x squared, minus 5 x, plus 3$
