The domain of the third piece of the graph is contained in the interval <u>B. (12, 20)</u>.
<h3>What is the domain of a graph?</h3>
The domain of a graph consists of all the input values shown on the x-axis.
The domain is the set of input values. The input values are shown on the x-axis, unlike the range that have output values shown on the y-axis.
The domain comprises the independent variables or values, which can be determined using the function, y = f(x).
Thus, the domain of the third piece of the graph can be determined in the interval <u>B. (12, 20)</u>.
