Is my work correct? Find x when f(x)=1. (This means find the input that gives an output of 1.) f(x)=2/2+2=2/4=2/2=1

    is it \[\frac{ 2 }{ x }+2 ~~\rm or \frac{ 2 }{ x+2 }\]

    okay cool so \[\huge\rm f(x) = \frac{ 2 }{ x+2 }\] f(x) =1 so substitute f(x) for 1 \[\rm 1=\frac{ 2 }{ x+2 }\] solve for x

    okay substitute x for 1 to check ur work \[\huge\rm 1=\frac{ 2 }{ \color{ReD}{1}+2 }\] both sides are equal ?

    so no x isn''t one yes right you should check ur answer if you get equal sides then yes one is right if both sides aren't equal then no

    it said find f(8) this means find the output of the function when x=4

    it's \[\frac{ 2 }{ 4+2 } =\frac{ 2 }{ 6}\]
