1.Circle the two bulbs you picked. 2.
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 _time, measured in hours.
The output of the function is energy usage, measured in ___kilo watts.
Identify the functional relationship between the variables. E(energy) is a function of T(time).
The graph of the function will show energy usage on the y axis and time on the x

4.Practice: Organizing Information (2 points) Use the data given to complete the table for your first bulb. DATA TABLE A Time (hours) xEnergy (kWh) yPoint (time, energy) (x, y)310 5.Practice: Organizing Information (2 points) Use the data given to complete the table for your second bulb. DATA TABLE B Time (hours) xEnergy (kWh) yPoint (time, energy) (x, y)310 6.Practice: Organizing Information (5 points: 1 point for labels, 2 points for each graph) Label the axes of the graph with "Time (hours)" and "Energy (kWh)." Plot the points from table A on the graph. Connect the points with a line. On the same graph, plot the points from table B and connect them with a line. 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? 10.Practice: Summarizing (1 point) The lights in the main room of the factory stay on for stretches of 9 hours. Which kind of light bulb would light this room with the least amount of energy?​
