Add to ORKGIn the function mapping x->f(x), the domain is all x values and the range is all f(x) values. If f(a)=f(b) implies a=b, the function is called injective, or one-to-one. If for any y in the range there is an x in the domain so that f(x)=y, the function is called surjective, or onto. If both conditions are met, the function is called bijective, or one-to-one and ontoComponente Curricular::Ensino Médio::Matemátic
