Function Notation
This video presents the same text shown beside it, spoken and on screen. It adds nothing the text does not say.
State
Function notation names the machine and its input at once: f(x) is the output of function f at input x.
Show
In f(x) = 2x + 3, the name is f, the input is x, and f(4) asks for the output at 4.
Watch for
f(x) is one symbol for an output, not f times x.
Builds on
- Nothing — this is a starting point.
Unlocks
- Nothing yet depends on this.
