The Number of Lumens (Time Rate of Flow of Light)

Question 11

Multiple Choice

The number of lumens (time rate of flow of light) L from a fluorescent lamp can be approximated by the model ​
L = -0.294x2 + 97.744x - 664.875, 20 ≤ x ≤ 90
​
Where x is the wattage of the lamp.
​
Use a graphing utility to select the graph of the function.Use the graph to estimate the wattage necessary to obtain 2400 lumens.
