Let f(x) be continuous on [a,b], differentiablein (a,b) and f(x) cancel(=)0 for all x in [a,b]. Then , there exists theta in (a,b), such that(f'(theta))/(f(theta)) is equal to

Answer»

`(1)/(a + THETA) - ( 1)/( B- theta )`
`( 1)/( a- theta ) + ( 1)/( b - theta )`
`(1)/( a+theta) + ( 1)/( b - theta )`
`( a+ b) theta `
