1:51:47 Determine if the given function has any points of discontinuity. Explain your reasoning.. fx=frac x2-b2x-b 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-b is 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.
