20. Rex, Ella, and Amy were asked to write and graph a quadratic function that includes
the points F (-3, 4) and G (0, 2).
Rex's graph shows a parabola that opens up and has a vertex at (0, 2). The graph
also passes through the points (-3, 4) and (3, 4).
Ella's graph shows a parabola that opens down and has a vertex at (-3, 4). The
graph also passes through the points (0, 2) and (-6,2).
Who is correct?
Amy's graph shows a parabola that opens up and has a vertex at (4,1). The graph
also passes through the points (-2, 4) and (0,2).

• No one is correct because at least 3 points are required to
determine and graph any quadratic function.
• Amy only
• All are correct because there is an infinite number of quadratic
functions that includes the two given points.
• Rex and Ella only
