Which of the following statements about the graph is true?

A. The point (-2.95, 0) is a minimum
B. The point (1.35, 0) is a maximum
C. The point (-0.8, -1.16) is a maximum
D. The point (-0.8, -1.16) is a minimum

Answer 1

 First of all, a graph has a minimum if it is shaped like a u (a quadratic). A graph has a maximum if it is shaped like an upside-down u. The vertex of the graph is a minimum or maximum based on the graph's shape.
