Evaluate the integral below by interpreting it in terms of areas in the figure.

Recall that the integral gives us the area under the curve, in case the area is below the x-axis the area is added as a negative number.
Therefore,
[tex]\int_5^{10}f(x)dx=A_3-A_4.[/tex]Substituting the given values for the areas, you get:
[tex]V=1-1=0.[/tex]
