[[ملف:Injective_function.svg|310px|"310px"|left|thumb|دوال تباينية. Diagramatic interpretation in the [[Cartesian plane]], defined by the [[Map (mathematics)|mapping]] ''f'' : ''X'' → ''Y'', where ''y'' = ''f''(''x''), ''X'' = [[Domain of a function|domain of function]], ''Y'' = [[range (mathematics)|range of function]], and im(''f'') denotes [[Image (mathematics)|image]] of ''f''. Every one ''x'' in ''X'' maps to exactly one unique ''y'' in ''Y''. The circled parts of the axes represent domain and range sets – in accordance with the standard diagrams above.]]
