10 Find the x values if any at which b f x is not continuous at a f x is not continuous at x 0 and f x has a removable discontinuity at x 0 x 0 1 C f x is not continuous at x 1 f x x x is not continuou d f x is not continuous at x 0 1 e f x is continuous for all real x and both the discontinuities are nonremovable x 1 and f x has a removable discontinuity at and f x has a removable discontinuity at x 0
