Select all of the statements that are true for the given parabola.
Naddik [55]

Answer:

A & D

Step-by-step explanation:

The parabola opens up, so the minimum value of y is at the point (1, -2) and the graph passes thru the x-axis at 3 and -1, so those are the x-intercepts.

The axis  of symmetry is x = 1, not y = -2 and the graph never has a maximum value.  Parabolas that open up never have a maximum value.
