Not every relation is a function. But every function is a relation. Function is just a part of relation.
The cubic function.
Range
The Mandelbrot graph is generated iteratively and so is a function of a function of a function ... and in that sense it is a composite function.
A formula or graph are two ways to describe a math function. How a math function is described depends on the domain of the function or the complexity of the function.
Resorcinol is a colouring agent for some chromatography experiments.
Resorcinol
Resorcinol is used to test honey to see if sugar has been added to the honey. After adding the solution of resorcinol to the honey boil it, if the mixture turns red it means sugar is added and the honey is not pure.
1,3-dihydroxybenzene
catechol
meta Dihydroxybenzene
Resorcinol is used as the complexing agent to provide the color reaction, although the exact nature of the colored product is not known. Since resorcinol favors electrophilic aromatic substitution, the reaction may be similar to the Molisch Test.
Resorcinol is 1,3-dihydroxy benzene, it is acidic and two 'OH' groups make the system sufficiently polar so it is soluble in polar solvent water.

I believe so.
Resorcinol resin glues are a high strength wood glue much used in vintage aircraft. Nowadays modern epoxies are taking it's place.
The formula is C6H6O2 and it is 1,3-dihydroxy benzene.
