Question

The function y=4(6)t models the number of people who have watched a video after t days. Graph the function to determine how many people initially watched the video by finding the y-intercept.

Answer 1

Interpreting the model as exponential y = 4·6^t, the y‑intercept is at t = 0:
y(0) = 4·6^0 = 4·1 = 4.

So the graph crosses the y‑axis at (0, 4) — initially 4 people watched the video.
