When Angel left his house in the morning, his cell phone battery was partially charged. Let
B
B represent the charge remaining in Angel's battery, as a percentage,
t
t hours since Angel left his house. A graph of
B
B is shown below. Write an equation for
B
B then state the
x
x-intercept of the graph and determine its interpretation in the context of the problem.
B =
The x intercept of the function is
Which represents
1.the charge of the battery when Angel woke up
2.the charge of the battery when Angel left his house
3.the number of hours until Angel’s phone dies
4.the percentage charge that Angel’s phone loses each hour
