    Graph the parabola

Strategies[]

Knowledge of any graphing technique will ensure success on this exercise, from a T-table to other more efficient methods.

  1. In the standard form a T-table can be the most efficient method to graph.
  2. If the vertex can be located, then symmetry ensures that values on one side will occur on the other side.
  3. If the given standard form of the parabola can be factored quickly, this will locate x-intercepts. Then the vertex is located half-way between the x-intercepts due to symmetry.

Real-life Applications[]

  1. Parabolas are used to model many situations in physics and business.
  2. Algebra has many applications in the real world.
