How to find x intercept how to find y intercept how to find axis of symmetry and how to find vertex

to find the x intercept, you have to find the part that will be crossing the x axis if you put it on a graph. to find the y intercept you have to find the part of the equation that will be crossing the y axis if you put it on a graph. The axis of symmetry is the line that divides a parabola into two parts that are mirror images. If the parabola opens up or down, the axis of symmetry is vertical. If the parabola opens right or left, the axis of symmetry is horizontal. The vertex is the point where the axis of symmetry intersects the parabola.

Hope I helped.

c. (3,2,6) is the answer.
