Interpreting Function Notation: Understanding f(x)

This lesson explains function notation, focusing on the common form F of X. It addresses misconceptions, such as confusing F of X with multiplication, and clarifies that function notation can use various variables. The lesson illustrates how function notation identifies a relation as a function, with examples like C of R for circumference and D of T for distance. These examples show how function notation highlights the dependency of outputs on inputs, reinforcing the understanding of functions.
