Determine if the function in the graph is one-to-one. The function is one-to-one. The function is not one-to-one. Determine if the function in the graph is one-to-one. The function is one-to-one. The function is not one-to-one.

Solution

If a horizontal line intersects a function\'s graph more than once, then the function is not one-to-one.

Hence, 1st question is not one to one and 2nd graph is one to one function.
