Not every relation is a function. But every function is a relation. Function is just a part of relation.
The cubic function.
Range
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.
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.

Cnidocytes
cnidocytes are specilized cells where nematocysts are storednematocysts are poisonous harpoons that are stored like coiled springscnidocytes are unique to the phylum Cnidaria (corals, sea anemones, hydrae, jellyfish, etc.).
Cnidocytes are important to cnidarians as these are the stinging cells used to catch prey and defend from enemies. It is a toxin which can disable prey and provide protection from adversaries. This can be used as a harpoon, sticky surface or lasso type action.
Jellyfish sting their prey using nematocysts, also called cnidocysts, stinging structures located in specialized cells called cnidocytes.
They're called cnidocytes. ^^
they are important because they help the sea jellies catch their prey.

it would make them less capable of capturing food
As to the functions: stinging nematocysts function primarily for the capture of prey, and secondarily as a defense mechanism. There are many types of nematocysts, such as those that function to inject toxins to immobilize prey, and those which serve to entangle and hold onto the intended meal by wrapping around it. Species of cnidarian jellies vary in the types of nematocysts they possess, and this can be used to some extent in classifying and identification.
