Observe the graph and table:
\Carla and Kimi are determining if ![\"\"](\"/test/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=70479dfdb3a538aa18ffc023e80681bb.png\")
is the function.
Find the correct solution of Carla and Kimi.
\Kimi; Linear equations that go through the origin are not always the identity.
\The identity linear function is ![\"\"](\"/test/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=dac06e1b1a772a89a96d188a81482454.png\")
.
