Learning Goal
Part of: Understand the concept of a function and use function notation — 1 of 3 cluster items
Understand function definition
**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).

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).
What you'll learn
- Define a function as a rule that assigns to each element of the domain exactly one element of the range
- Use and interpret function notation f(x), understanding that f(x) denotes the output of function f for input x
- Explain the meaning of domain and range in the context of a function
- Recognize that the graph of a function f is the graph of the equation y = f(x), connecting function notation to graphical representation
- Transition from informal Grade 8 function language to formal high school terminology and notation
