Devon is having difficulty determining if the relation given in an input-output table is a function.
marco explains to him that in order to tell if the relation in the table is a function, devon needs to check if any of the output values are repeated. if they repeat and have different input values, the relation is not a function.

answer: -2+√x,-2-√x

i hope this , i don't know if you're looking for a pair or not.

i think the answer would be c

answer: the proof is mentioned below.

step-by-step explanation:

since, given:   lines bc = ef

prove:   lines ac > ef

          statements                                           reason

1. bc=ef                                           1. given

2. ac= ab+bc                                 2. because b is the point between the  

                                                            line segment ac

3.   ac > bc                                       3. because if a line segment is equal to

                                                          the sum of two line segments then it is

                                                          always greater then each of these

                                                          individual line segments

4. ac > ef                                         4. by equality property.
