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.
In xanthophyll there are 3.
A xanthophyll is a derivative of a type of carotene, a plant pigment commonly yellow in colour.
These are carotenoids
Carotene and xanthophyll are accessory pigments that assist in capturing light energy during photosynthesis, but they absorb different wavelengths of light compared to chlorophyll. Additionally, carotene and xanthophyll help expand the range of light that can be utilized by plants for photosynthesis and provide photoprotection by dissipating excess energy.
Autumn is the best season for xanthophyll because the cooler temperatures and shorter days trigger the breakdown of chlorophyll, revealing the yellow and orange pigments of xanthophyll that were previously masked. This leads to the vibrant foliage colors that are characteristic of the season.
Plant tissues that contain only xanthophyll appear yellow. Xanthophyll is a yellow pigment typically found in the chloroplasts of plant cells and is responsible for giving certain plants their yellow coloration.
Xanthophyll
Xanthophyll's are usually what create yellow pigments in leaves. They do not require light for synthesis, so they are present in all young leaves as well as in etiolated leaves.
Photosynthetic pigment consisting of chlorophyll a & b, carotene and xanthophyll.
chlorophyll a & b, Carotene and xanthophyll etc.
There are mainly Caratinoids. They are Xanthophyll and Carotene mainly.
It's the yellow pigment in leaves. You see it in the fall after the chlorophyll is used up.
