Access Point #: MAFS.912.A-SSE.2.AP.3c

Given a quadratic expression, explain the meaning of the zeros graphically (e.g., for an expression (x - a) (x - c), a and c correspond to the x-intercepts (if a and c are real).
Clarifications:

Essential Understandings

Concrete:

  • Use a tool to determine whether the quadratic function crosses the x-axis. Click Here
  • Use a graphing tool or graphing software to find the roots (where the function intersects the x-axis) of a function.
  • Match the quadratic equation with its corresponding graph.
  • Match the graph of a quadratic equation with its roots (zeros).
Representation:
  • Understand the following concepts and vocabulary: root, factor, quadratic, integer, real number, quadratic equation, quadratic formula, square root, solution, terms, coefficient, intercept, intersect, zero.
  • Understand that a quadratic function that intersects the x-axis has real roots (zeros).

Category: Access Points
Date Adopted or Revised: 07/14
Cluster: Write expressions in equivalent forms to solve problems. (Algebra 1 - Supporting Cluster) (Algebra 2 - Major Cluster)

Clusters should not be sorted from Major to Supporting and then taught in that order. To do so would strip the coherence of the mathematical ideas and miss the opportunity to enhance the major work of the grade with the supporting clusters.
