Question 1 of 10

2. Given two polygons, the first one having more sides than the second, let the following rule describe how to map the first polygon to the second polygon. (To help illustrate, refer to the two polygons pictured below.) Label the vertices of each polygon A, B, C, etc. Then, each vertex of polygon 1 is mapped to its corresponding vertex on polygon 2 (A to A, B to B, etc.). For all extra vertices of the first polygon (in this case G and H), they map to the final vertex of the second polygon (in this case to F). Is this rule a function? If not, why not?

A.Yes, this is a function.

B.No, functions relate only to equations and graphs.

C.No, because multiple vertices of the first polygon are mapped to the same vertex on the second polygon, which is the same as failing the vertical line test.

D.No, because this is not continuous; there is only a finite set of points, while functions (graphs) are an infinite set of points.

Our quizzes are helping you to develop the skills and knowledge required to take the TSI Math subtest successfully. These math quizzes address solving problems and some questions can be slightly different from problems found in the book.

For these problems, you’ll have to adapt the things you’ve learned to be able to solve these new problems.

When you have missed a question, our quiz will show you the correct answer which allows for self-diagnosing the mistake.

Then, you can work on similar problems until you understand the topic and answer the question correctly.
