Lesson 18: Using Functions to Model Battery Power
18.1: Devices
Think about an electronic device with a battery that you have to charge on a regular basis.
1. What device is it?
2.
When you are using the device, about how long does it take the battery to go from
100% charged until the time you plug it in again to recharge?
3.
About how long does it take to charge to 100% starting from 0% or nearly 0%?
4.
Suppose you plugged in your device when the battery was 50% charged.
How long do you think it would take to recharge the device to 100% compared to the
time it would take if the device was at 0%? Would it be exactly half the time, more than
half the time, or less than half the time it would take if starting from 0%?
