Use the Horizontal Line Test to determine whether<span> a </span>function<span> is one-to- one. A </span>function<span> is one-to-one if and only if no </span>horizontal line<span> intersects its graph more than once. Example: From the graph at the left, </span>determine whether<span> the </span>function<span> is one- to-one and thus has an </span>inverse<span> that is a </span>function<span>. </span> Hope this Helps! Have A Wonderful Day! :)
