True, sometimes true, or never true? The area
of the region between the graphs of the
continuous functions y=f(x) and y=g(x) and the
vertical lines x=a and x=b (a<b) is
b
S[f(x)—g(x)]dx.
a
Choose the correct answer below.
A.
The given integral is sometimes equal to the
area between y=f(x) and y=g(x). It is equal to
the area only if f(x)≥g(x) on the interval [a,b].
B.
The given integral is never equal to the area
between y=f(x) and y=g(x). The correct
integral is
b
S[f(x)−g(x)]dx.
a
C.
The given integral is always equal to the area
between y=f(x) and y=g(x), since that is the
definition of the area between two curves.
D.
The given integral is sometimes equal to the
area between y=f(x) and y=g(x). It is equal to
the area only if f(x)≤g(x) on the interval [a,b].
