Essential Understandings
Concrete:
- Use a tool to determine whether the polynomial 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 polynomial function with its corresponding graph.
- Match the graph of the polynomial function with its roots (zeros).
- Understand the following concepts and vocabulary: root, factor, quadratic, integer, real number, quadratic equation, quadratic formula, polynomial, degree, exponent, square root, solution, terms, coefficient, intercept, intersect, zero.
- Understand that a function that intersects the x-axis has real roots (zeros)
- Understand that a root is where a function crosses the x-axis.
- Understand that the degree (largest exponent) of a polynomial determines the type and shape of the graph.

Cluster:
Understand the relationship between zeros and factors of polynomials. (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. |
