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

 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.
