Function Notation

50 Minute Class, Algebra 1, Curriculum

Learning Goal: Understand the features of function notation and how to evaluate functions.




  • Common Core
    • HSF.IF.A.1 – Understand that a function from one set (called the domain) to another set (called the range) assigns to each element of the domain exactly one element of the range. If f is a function and x is an element of its domain, then f(x) denotes the output of f corresponding to the input x. The graph of f is the graph of the equation y = f(x).
    • HSF.IF.A.2 – Use function notation, evaluate functions for inputs in their domains, and interpret statements that use function notation in terms of a context.
  • TEKS (2015-16)
    • A.12(B) – evaluate functions, expressed in function notation, given one or more elements in their domains
