Graphs of Exponential Functions
This video presents the same text shown beside it, spoken and on screen. It adds nothing the text does not say.
State
The graph of f(x) = bˣ passes through (0, 1), has domain all reals and range (0, ∞), and hugs the horizontal asymptote y = 0 on its shrinking side.
Show
2ˣ runs through (−1, 1/2), (0, 1), (1, 2); far left, 2⁻¹⁰ ≈ 0.001 — near the floor, never on it.
Builds on
- Nothing — this is a starting point.
Unlocks
- Nothing yet depends on this.
