The graph described is the graph of a quadratic function.
The x-intercept of the function is at; (8, 0).
<h3>What type of function is described by the graph?</h3>
It follows from the description box of the graph that it begins in the third quadrant, and rises through a series of points in the first quadrant before it exits the first quadrant.
Hence, it follows that the graph is a quadratic function and its x-intercept is at point; (8,0).

Option B:
Solution:
Given sound level = 120 decibel
To find the intensity of a fire alarm:
where 
Step 1: First divide the decibel level by 10.
120 ÷ 10 = 12
Step 2: Use that value in the exponent of the ratio with base 10.
Step 3: Use that power of twelve to find the intensity in Watts per square meter.
Now, do the cross multiplication,
Option B is the correct answer.
Hence .
6x4 = 24
Therefore, 24 is your answer.
