Look at the functions in the table below.

Is there a property or feature that is shared by two functions in a row but not the third? If so, we can say that the third function is the odd one out.

Find a reason why each function in the table could be the odd one out in its row.

\(y=\sin x^2\) | \(y=\ln{x^2}\) | \(y=\tan x (\sec^2 x-1)\) |

\(y=9x^2-6x+1\) | \(y=\ln{3x}\) | \(y=\sqrt{3x-1}\) |

\(y=e^{5x}\) | \(y=\dfrac{1}{x^2+4x+4}\) | \(y=e^{x+4}\) |

Can you also find an odd one out within each column?
