which set of data could be reasonably modeled by a quadratic function? graph a graph b a. both graphs b. graph a c. graph b d. neither graph
Answer
Explanation:
Step1: Recall quadratic - function graph shape
A quadratic function has a graph in the shape of a parabola. A parabola is a U - shaped or inverted U - shaped curve.
Step2: Analyze Graph A
Graph A appears to have a more or less linear trend. The points do not follow a U - shaped or inverted U - shaped pattern.
Step3: Analyze Graph B
Graph B shows a U - shaped pattern. The points first decrease and then increase, which is characteristic of a quadratic function.
Answer:
C. graph B
