Identify the values of an inverse function given a function modeled in a table or graph.
Clarifications:
Essential Understandings
Concrete:
- Identify a function.
- Identify the x and y variables.
- Identify the domain and range of a function.
- Identify the inverse of a function.
- Use tools (patty paper, transparencies, mirror, mira, graphing calculator) to reflect the original function.
- Use paper folding to determine the mirror image.
- Understand the following concepts and vocabulary: domain, range, inverse, function, input, output, graph coefficient, slope, reflect, reflection, mirror image.
- Understand that the inverse function creates a mirror image of the original function.
- Understand that the domain (x) and range (y) values of the original function are opposites of each other in the inverse function.

Cluster:
Build new functions from existing functions. (Algebra 1 - Additional Cluster) (Algebra 2 - Additional 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.
