A function is 1:1 if it passes the vertical line test and the horizontal line test as well

anonymous · Answer

This means that if you place a line on the graph then the function passes over the line only once! either vertically or horizontally

anonymous · Answer

Therefore a vertical parabola fails the test in the Y axis :D

anonymous · Answer

So how would i answer that question in a few short sentences?

anonymous · Answer

A 1:1 function has a single value for each element and it passes the horizontal and vertical line test.
