Question 1182384

By definition, the inputs in a function have only one output.

if each element in the domain is matched with exactly one element in the range, you have a function

{({{{-8}}}, {{{3}}}), ({{{3}}}, {{{5}}}), ({{{5}}}, {{{6}}}), ({{{6}}},{{{ 8}}})}


({{{-8}}}, {{{3}}})->{{{-8}}} matched with {{{3}}}
({{{3}}}, {{{5}}})->{{{3}}} matched with {{{5}}}
({{{5}}}, {{{6}}})->{{{5}}} matched with {{{6}}}
({{{6}}},{{{ 8}}})->{{{6}}} matched with {{{8}}}

=>each element value of {{{x}}} is matched with exactly one {{{y}}}, you have a function

domain: {{{-8}}},{{{3}}},{{{5}}},{{{6}}}

range:{{{3}}},{{{5}}},{{{6}}}, {{{8}}}
