Question

1. which are points of discontinuity?

holes and asymptotes
intercepts and slopes
asymptotes and intercepts
holes and intercepts

Explanation:

Points of discontinuity in rational functions are where the function is not defined or has breaks. Holes occur at common factors of numerator and denominator (removable discontinuity), and asymptotes (vertical, horizontal, slant) are non-removable discontinuities where the function approaches infinity or a line. Intercepts and slopes are not related to discontinuity.

Answer:

holes and asymptotes
