Standard 3 : Create new functions from existing functions.
Cluster Standards

This cluster includes the following benchmarks.

Visit the specific benchmark webpage to find related instructional resources.

  • MA.912.F.3.1 : Given a mathematical or real-world context, combine two functions, limited to linear and quadratic, using arithmetic operations. When appropriate, include domain restrictions for the new function.
  • MA.912.F.3.2 : Given a mathematical or real-world context, combine two or more functions, limited to linear, quadratic, exponential and polynomial, using arithmetic operations. When appropriate, include domain restrictions for the new function.
  • MA.912.F.3.3 : Solve mathematical and real-world problems involving functions that have been combined using arithmetic operations.
  • MA.912.F.3.4 : Represent the composition of two functions algebraically or in a table. Determine the domain and range of the composite function.
  • MA.912.F.3.5 : Solve mathematical and real-world problems involving composite functions.
  • MA.912.F.3.6 : Determine whether an inverse function exists by analyzing tables, graphs and equations.
  • MA.912.F.3.7 : Represent the inverse of a function algebraically, graphically or in a table. Use composition of functions to verify that one function is the inverse of the other.
  • MA.912.F.3.8 : Produce an invertible function from a non-invertible function by restricting the domain.
  • MA.912.F.3.9 : Solve mathematical and real-world problems involving inverse functions.

Formative Assessments
  • Furniture Purchase: Students are asked to write two explicit functions given verbal descriptions in a real-world context, compose the two functions, and explain the meaning in context.

  • How Much Bacteria?: Students are asked to write and combine an exponential and a constant function from a verbal description to use when answering a related context question.
