Q2W10 Algebra

MAFS.912.F-LE.1.3  Recognize that sequences are functions, sometimes defined recursively, whose domain is a subset of the integers.  For example, the Fibonacci sequence is defined recursively by f(0) = f(1) =1, f(n + 1) = f(n) + f(n-1) for n>=1.

MAFS.912.F-LE.1.2  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).

• create a table from a list of numbers (sequence) by making the term number (position) the inputs and the elements the outputs.

• define an arithmetic sequence as a sequence of numbers that is formed so that the difference between consecutive terms is always the same known as a common difference.

• recognize arithmetic sequences as linear functions.

• explain that a recursive formula tells me how a sequence starts and tells me how to use the previous value(s) to generate the next element of the sequence.

• explain that an explicit formula tells me how a sequence starts and tells me how to find any term of the sequence by knowing the difference by which the sequence increases or decreases.

• find an explicit or recursive rule for a sequence.

• write specified terms for a sequence, defined explicitly or defined recursively.

• • describe the algebraic process used to construct the linear function that passes through two points.

  • decide if a graph, verbal description, data, or sets of ordered pairs models an arithmetic sequence (linear) and write the equation.

  • • distinguish between explicit and recursive formulas for sequences.

    • identify the quantities being compared in a real-world problem.

    • write an explicit function, define a recursive process, or complete a table of calculations that can be used to mathematically define a real-world context.

    • write a recursive definition for a sequence that is presented as a sequence, a graph, or a table.

    • • create equations and inequalities that best models the constraints of a real- world problem.

      • interpret the solution of a real-world context as viable or not viable.

      • interpret the meaning of the slope in terms of the units stated in the data.
      • interpret the meaning of the y-intercept in terms of the units stated in the data.
      • express linear functions in slope intercept form, standard form, and point slope form.
