Vertex and Zeros of a Quadratic in Context: Sample Algebra 1 EOC Questions

For a thrown ball or a profit model, the vertex is the maximum or minimum and the zeros are where the quantity reaches zero. Students find both from an expression or an equation and say what each means in the situation.

How the Algebra 1 EOC tests this benchmark

Every item on this benchmark is real-world, so the interpretation sentence carries as much weight as the computation. Typical questions ask for the maximum height, the time it occurs, or when the object lands. Drop-down and multiple choice items pair a value with its meaning, and equation editor items ask for one coordinate of the vertex.

Skills students need

  • Find the vertex from standard or vertex form
  • Find the zeros of a quadratic
  • Interpret the vertex as a maximum or minimum in context
  • Interpret a zero in the units of the situation

Question 1EasyMultiple Choice
A ball is kicked from the ground, and its height in feet after tt seconds is h(t)=−16t2+80th(t) = -16t^2 + 80t. What does the zero t=0t = 0 mean in this situation?
