State
Evaluating an exponential function substitutes the input into the exponent and computes by the exponent rules.
Show
For f(x) = 3·2ˣ: f(3) = 3·2³ = 3·8 = 24 — the exponent first, the coefficient after.
Watch for
The base carries the exponent; the coefficient never does.
Builds on
- Nothing — this is a starting point.
Unlocks
- Nothing yet depends on this.
