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
y=input x=output
what is f(x) function ?
f(x)= y
the function is 2/x+2
is it \[\frac{ 2 }{ x }+2 ~~\rm or \frac{ 2 }{ x+2 }\]
the one after or (the second one)
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
!!OH Duh im finding x so i did it wrong right?
i said that x was 2 according to my calculations
yes right i don't know why u replaced `x` with `2`
x is 1
okay substitute x for 1 to check ur work \[\huge\rm 1=\frac{ 2 }{ \color{ReD}{1}+2 }\] both sides are equal ?
NO
OHHHH OK SO THEY HAVE TO EQUAL THE SAME!!! THANK YOU SO MUCH IM NEW TO THIS
:di got it let me try another #
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
ok but there is one question where it says x=4 but when i plugged in 4 it wasnt equal
|dw:1441162289198:dw|
f(8) is not equal to 3 or 2/6
|dw:1441162547995:dw| bot sides are equal ?
