Question

what is the significance of the point (-3, 18)? select all correct options y - intercept x - intercept axis of symmetry vertex

Explanation:

• A y-intercept has an x-value of 0, so (-3,18) is not this.
• An x-intercept has a y-value of 0, so (-3,18) is not this.
• The axis of symmetry is a vertical line (form $x=h$), not a point.
• The vertex of a parabola is its highest or lowest point, which matches the peak shown in the graph at (-3,18).

Answer:

vertex
