Question

Use the image to answer the question.

A parabola is graphed on a coordinate plane. The x-axis ranges from negative 6 to 5 in increments of 1. They y-axis ranges from negative 2 to 16 in increments of 2.
The parabola passes through coordinates left parenthesis negative 5 comma 0 right parenthesis and left parenthesis 3 comma 0 right parenthesis. The vertex has coordinates left parenthesis negative 1 comma 16 right parenthesis.


Identify the vertex and axis of symmetry of the parabola.

Answer 1

Vertex: (-1, 16)

Axis of symmetry: the vertical line x = -1 (the vertex's x-coordinate; indeed (-5,0) and (3,0) are symmetric about x = -1).
