Determine if the given function has any points of discontinuity. Explain your reasoning.
There is a point of discontinuity at x = b because the denominator has the factor x-b.
There are points of discontinuity at both x = -b and x = b because the numerator has factors of x + b and x-b.
There is a point of discontinuity at x = b only because the factor of x-bis common to both the numerator and
denominator
There is a point of discontinuity at x = -b only because the factor of x-b is common to both the numerator and
denominator and factors out.
