What is range of the inverse of the relation {(1, 7), (-2, 4), (5, 6), (2, 8)} a. {1, 2,5} b. {-4, 6, 7, 8} c. {1, 5} d. {-4, 7, 8}

The answer should be the domain of this relation. {-2, 1, 2, 5} but I do not see that as one of your answer choices.

The inverse of a relation is when you switch the domain and range.  In other words, the domain of the original relation becomes the range of the inverse.

You have 2 sides that are 2 cms and you have 6 sides that are 1/2 cm and you have 4 sides that are 1 cm. the smallest sides are 1/2 the medium sized sides are 1 and the smallest are 1/2. so to find the perimeter you have to add them all up together so your answer will be 11 cm's
