The domain is (1,3,5,7,9) and the range is (2,4,6,8,0)
<span><u><em>The correct answers are:</em></u>
a line of symmetry will connect a vertex and a midpoint of an opposite side
it has 7-fold symmetry.
<u><em>Explanation</em></u><span><u><em>: </em></u>
A line of symmetry is a line that we can use to <u>"fold"</u> a figure in half. In order to do this, we will "fold" the figure from a vertex to the middle of the side opposite the vertex.
Since there are 7 vertices, there will be 7 lines of reflection.</span></span>
