This week in Pre Calculus 11 we learned about several terms in graphing.

Parabolas are identical on each side of the axis of symmetry.

Axis of symmetry:

the line in the middle of the parabola.

Vertex:

the highest or lowest point of the parabola, whichever is finite.

Root:

Roots are another way to say X-intercepts (where the parabola crosses the X-axis).
