So this actually is not a specific homework question, but i was wondering how you find the domain of a function. for example, if the function was x^2 + x + 5 how would you find the domain? ? , also no rush for an answer. i will be patient. : )

Danny draws a transversal, t, on two parallel lines ab and cd, as shown below: he makes the following table to prove that the alternate interior angles are equal: which is the missing justification? (6 points) corresponding angles formed by a transversal on parallel lines are supplementary. corresponding angles formed by a transversal on parallel lines are congruent. co-interior angles formed by a transversal on parallel lines are congruent. co-exterior angles formed by a transversal on parallel lines are congruent.
