Let math xmlns=http://www.w3.org/1998/Math/MathML class=wrs_chemistrymi mathvariant=normalA/mimo=/momi mathvariant=boldR/mimo-/momo{/momn3/mnmo}/mo/math and math xmlns=http://www.w3.org/1998/Math/MathML class=wrs_chemistrymi mathvariant=normalB/mimo=/momi mathvariant=boldR/mimo-/momo{/momn1/mnmo}/mo/math. Consider the function math xmlns=http://www.w3.org/1998/Math/MathML class=wrs_chemistrymif/mimo:/momi mathvariant=normalA/mimo→/momi mathvariant=normalB/mi/math defined by math xmlns=http://www.w3.org/1998/Math/MathMLmif/mimo(/momix/mimo)/momo=/momfencedmfracmrowmix/mimo-/momn2/mn/mrowmrowmix/mimo-/momn3/mn/mrow/mfrac/mfenced/math. Is math xmlns=http://www.w3.org/1998/Math/MathMLmif/mi/math one-one and onto? Justify your answer.
