9.8 Geometric Sequences as Exponential Functions

Standard(s):

  • F.IF.A.3: Recognize that sequences are functions, sometimes defined recursively, whose domain is a subset of the integers.
  • F.BF.A.2: Write arithmetic and geometric sequences both recursively and with an explicit formula, use them to model situations, and translate between the two forms.
  • F.LE.A.2: Construct linear and exponential functions, including arithmetic and geometric sequences, given a graph, a description of a relationship, or two input-output pairs (include reading these from a table).

Essential Question:

  • How can the relationship between quantities best be represented?
  • In what ways can the problem be solved, and why should one method be chosen over another?
  • When does a function best model a situation?
  • In what ways can functions be built?
  • How can I use algebra to describe the relationship between sets of numbers?
  • In what ways can the choice of units, quantities, and levels of accuracy impact a solution?

Learning Target:

  • I can identify the pattern in a sequence. (Analyze)
  • I can write a function rule for a sequence. (Synthesize)
  • I can define explicit and recursive expression of a function. (Knowledge)
