Summary

[edit]
Description
English: Shows (a part of) the graph of the function y=x2 (red) which is neither injective (as it maps e.g. both -5 and +5 to 25) nor surjective (as it doesn't map any real number to e.g. -14), and of the function y=2x+20 (green) which is both injective and surjective (hence bijective)
