Is either of the following equations correct? Give reasons for your answers. a. x -dx = x In x + c b. x -dx = x In x + Cx X X - . = Choose the correct answer below. O A. Both equations are correct because C and Cx are both arbitrary constants. O B. Equation (b) is correct because -dx = In x| + C, so x -dx = x In |x|+ Cx. X X O C. Equation (a) is correct because dx = In x| + C, so x -dx = x In |x|+C. X O D. Neither equation is correct because - -dx is only defined for integer values of x. X
