Question

Select all of the statements that are true for the given parabola.

A. The minimum is (1,-2).
B. The line of symmetry is y=-2.
C. The maximum is (1,-2).
D. The x-intercepts are (3,0) and (-1,0).

Answer 1

A & D

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.
