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.
A gemmae cup is a cup-shaped structure found in liverworts that contains gemmae, which are small, asexual reproductive structures. Gemmae cups are usually located on the upper surface of the thallus (body) of the liverwort plant. They are specialized for dispersing gemmae, which can give rise to new plants under suitable conditions.
gemmae
Gemmae
They are one- to several-celled or sometimes multicellular propagules called gemmae that are produced on the margins and surfaces or at the tips.
A small cellular body or bud that can separate to form a new organism.
Gemma cups are a specialized structure found in the liverwort Marchantia species that produce gemmae—asexual reproductive structures. Gemmae are essential for the vegetative reproduction of Marchantia, allowing them to propagate rapidly and colonize new habitats. This efficient method of reproduction enables Marchantia to spread and establish populations successfully in various environments.
The small bits of tissue carried in cup-like structures on liverworts are called gemmae. Gemmae are a means of asexual reproduction for liverworts, allowing them to reproduce quickly and efficiently.
gemmae
Liverworts are non-vascular plants that lack true stems and leaves. They reproduce via spores or asexual, through gemmae cups. Liverworts grow close to the ground and are commonly found in moist environments.
The Latin word for 'gem' or 'jewel' is 'gemma'. The word 'jewelry' implies more than one gem or jewel. So the Latin equivalent is gemmae. The jeweller is 'qui gemmas vendit', 'qui gemmas sculpit', which means '[the one] who sells jewels, who cuts jewels'.
