Question

use the graph to fill in the missing parts.
the y - intercept is ______.
the axis of symmetry is ______.
the vertex is ______.
the y - intercept is (0, - 1) (type an ordered pair)
the axis of symmetry is \square (type an equation)

Explanation:

Step1: Identify axis of symmetry

The axis of symmetry of a parabola is the vertical line passing through its vertex. From the graph, the vertex lies on the vertical line $x=0$.

Step2: Identify the vertex

The vertex is the lowest point of the upward-opening parabola, which is at the coordinate $(0, -2)$.

Answer:

The y-intercept is $(0, -1)$
The axis of symmetry is $x=0$
The vertex is $(0, -2)$
