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.
The noun 'hyperemia' is an uncountable noun, a word for a physical condition.
Hyperemia
Hyperemia of the mucous membrane refers to an increased blood flow to the mucous lining of a specific area in the body. This can result in redness, swelling, and irritation of the mucous membrane due to increased blood supply. Hyperemia can be caused by various factors such as inflammation, infection, or irritation.
Erythema is the physical sign of redness of an ectodermal structure like skin or the exocervix. It is caused by Hyperemia, which is the presence of increased blood flow to a particular structure. Erythema is a physical sign, while Hyperemia is a physiologic process. Hyperemia can also occur in other parts of the body like in a myocardial infarct.
Hyperemia can be caused byaldosterone hormone (which increases blood volume, therefore, icreases blood pressure). Either way by physical exercise -when someone is training,working out- which activates sympaticus and parasympaticus.
Abnormal focal hyperemia refers to an increased blood flow to a specific localized area in the body. This can be a sign of inflammation, infection, or tissue damage in that particular region. It is important to identify the underlying cause of the abnormal hyperemia to determine the appropriate treatment.
chemicals released by the injured tissue cells and leukocytes cause the VASODILATION of the arterioles in the injured area and cause the local hyperemia to form accounting for the redness and heat.
Hyperemia is basically the increase of blood flow to a particular organ in the body. Therefore concerning an injury to the tibial metaphysis, excessive blood will migrate towards joints. It is also known to cause excessive bone growth.
Rubor (Redness) - Vasodilation, local hyperemia that occurs when atrioles dilate. (remember that hyperemia is due to an increased metabolism often induced by a fever.) Tumor(Swelling) - Exudate, fluid containing clotting factors and antibodies seeps from the blood into the tissue spaces. Calor(Heat) - Vasodilation, local hyperemia that occurs when atrioles dilate. (remember that hyperemia is due to an increased metabolism often induced by a fever.) Dolor(Pain) - Edema presses on adjacent nerve endings contributing to the sensation of pain. Also the sensitizing effects of releasing Agranulocytes(prostaglandins and kinins.

Skin injury of any kind will often cause increased blood-flow (hyperemia) in the capillaries immediately below the skin, which results in erythema, which is a redness in the skin (erythr/o = red).
