Question

What is true about the function graphed below?

see image v v v

A. The coordinates of the vertex are (3, 0).
B. The function graphed is look at the picture.
C. The axis of symmetry is the x-axis.
D. The axis of symmetry is the y-axis.

Answer 1

D. The axis of symmetry is the y-axis.

Explanation:

The vertex is at coordinates (0, 3). Since this parabola opens vertically, its axis of symmetry is the x=coordinate of the vertex: x = 0. That is the equation of the y-axis.

The axis of symmetry is the y-axis.
