State
Evaluating a function means substituting the input for every appearance of the variable and computing the output.
Show
For f(x) = 2x + 3: f(4) = 2(4) + 3 = 11. The input 4 replaces x everywhere x appears.
Watch for
Substitute in parentheses; the input arrives as a block.
Builds on
- Nothing — this is a starting point.
Unlocks
- Nothing yet depends on this.
