I really need help with all of these!!

YOUR ASSIGNMENT: Factory Lighting Problem

You are deciding whether to light a new factory using bulb A, bulb B, or bulb C.

Which bulb would be better to use on the factory floor?
Which bulb would be better to use in the break room?
To answer these questions, you will compare the energy usage of the three bulbs. The amount of energy the lights use is measured in units of kilowatt-hours. A kilowatt-hour is the amount of energy needed to provide 1000 watts of power for 1 hour.

1. Circle the two bulbs you picked.

- I picked incandescent and fluorescent

- the information for this is the following: The energy usage of the incandescent bulb after 3 hours is 0.3 kWh, and after 10 hours the energy usage is 1.0 kWh.
The energy usage of the fluorescent bulb after 3 hours is 0.35 kWh, and after 10 hours the energy usage is 0.9 kWh.
Use these data to create graphs and compare the bulbs' energy usage



3. Practice: Summarizing (3 points)
Fill in the blanks.

The energy usage of a light bulb is a function. The input for the function is _________, measured in hours.

The output of the function is energy usage, measured in ____________.

Identify the functional relationship between the variables. _________________ is a function of _________________.

The graph of the function will show energy usage on the _____________ axis and time on the _______________ axis.

4. see the picture attached below
5. See picture attached below


7. Practice: Summarizing (1 point)
Classify each of your graphs as increasing, decreasing, or constant.

First bulb: ___________________


Second bulb:___________________

8. Practice: Summarizing (2 points)
Fill in the blanks.

First bulb: When 3 is the input, the output is _____. When 10 is the input, the output is _______.


Second bulb: When 3 is the input, the output is _____. When 10 is the input, the output is _______.

9. Practice: Summarizing (1 point)
The workers leave the lights on in the break room for stretches of about 3 hours. Which light bulb would light this room using the least amount of energy?
