The function y\ =\ 4\left(6\right)^{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.
The y-intercept of a graph is the point where the graph intersects the y-axis. At this point, the value of x is 0.
To find the y-intercept of the function y = 4(6)^t, substitute x = 0 into the equation:
y = 4(6)^0
y = 4(1)
y = 4
Therefore, the y-intercept is 4. This means that initially, 4 people watched the video.
