Unformatted text preview: f ( x ) = 0 for x [ a, b ]. 3. Let f, g : [ a, b ] R . Suppose that f is dierentiable and nondecreasing on [ a, b ], and f is continuous on [ a, b ], and that g is dierentiable on [ a, b ] and g is integrable on [ a, b ], and g is strictly positive on ( a, b ) but g ( a ) = g ( b ) = 0. Then, show that f is constant on [ a, b ] if and only if i b a f ( x ) g ( x ) dx = 0 . 1...
