To find the y-intercept, we need to plug in t=0 into the function y=4(6)^t and solve for y.
y=4(6)^0
y=4(1)
y=4
Therefore, the y-intercept is at the point (0,4). This means that initially, 4 people watched the video.
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.
