Abstract terminology and symbols	Concrete example from dynamic tent
$y=f\left(x\right)$	Height is a function of Base; $f\left(Base\right)=Height$
$x=f^{-1}\left(y\right)$	Base is a function of Height; $f^{-1}\left(Height\right)=Base$
Domain of $y=f\left(x\right)$	The different possible values for Tent Base Length
Range of $y=f\left(x\right)$	The different possible values for Tent Height
Domain of $x=f^{-1}\left(y\right)$	The different possible values for Tent Height
Range of $x=f^{-1}$(y)	The different possible values for Tent Base Length
