yields a local maximum. Note that f(e) = .(D) Since is always positive, there are no
reversals in motion along the line.(B) The slope field suggests the curve shown above as a particular
solution.(D) Since , f is discontinuous at x = 1; the domain of F is
therefore x > 1. On [2, 5] f(x) < 0, so , which
is positive for x > 1.
