For a trapezoid:
the area equals the product of half the sum of the two bases' length and the normal height between them
so that, we can write:

Answer:
D
Step-by-step explanation:
To evaluate the value of the function at 3, draw vertical line and find the point of intersection of this line with the graph of the given function.
You can see that the vertical line has two common points with the graph: (3,5) and (3,7). The first point (3,5) is solid (filled), so this point belongs to the graph and it is the point of intersection. The second point (3,7) is open point (not filled), so this point does not belong to the graph, so it cannot be the point of intersection.
Hence,
