6. GSE Algebra I Standards: Today’s Question:
Understand the concept of a function and use function notation
MGSE9-12.F.IF.1 Understand that a function from one set (the input, called the domain) to another set (the output, called the range) assigns to each element of the domain exactly one element of the range, i.e. each input value maps to exactly one output value. If f is a function, x is the input (an element of the domain), and f(x) is the output (an element of the range). Graphically, the graph is y = f(x).
MGSE9-12.F.IF.2 Use function notation, evaluate functions for inputs in their domains, and interpret statements that use function notation in terms of a context.
Today’s Question:
What is a function, and how is function notation used to evaluate functions?
Standard: MCC9-12.F.IF.1 and 2
