Formalizing Relations and Functions

Formalizing Relations and Functions

Objective: 

• To determine whether a relation is a function
• To find domain and range and use function notation

I CAN use the definition of a function to determine whether a relationship is a function given a table, graph or words.

I CAN identify x as an element of the domain and f(x) as an element in the range given the function f.

I CAN identify that the graph of the function f is the graph of the function y=f(x).

I CAN use f(x) notation when a relation is determined to be a function.

I CAN evaluate functions for inputs in their domains.

I CAN interpret statements that use function notation in terms of a context in which they are used.

Standards

• MAT-HS.F-IF.01  Understand that a function from one et (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).
• MAT-HS.F-IF.02  Use function notation, evaluate functions for inputs in their domains, and interpret statements that use function notation in terms of a context.
