Abattery is charged. the percentage of the battery’s capacity that is charged as a function of time (in minutes) is graphed.

what does the y-intercept represent in the context of the problem?

The function that models a battery charge has to be a decreasing function, because while the time increases, the energy of the battery will decrease.

Being said that, the initial condition is the y-interception point, because it states the charged battery. In other words, the y-interception refers to the initial instant where the battery is full, when t = 0, because there's no time wasted at that point.

The y-intercept represents the whole charge of the battery, which will decrease over time.
