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 resistance of a photoresistor is inversely proportional to the intensity of the light on it.

What does a photoresistor do ?Photoresistors (also often called phototransistorsor CdS photoconductive photocells; use 'photocell' for digikey) are simple resistors that altar resistancedepending on the amount of light place over them.
You probably can't. The sensitivity will be a result of the manufacturing process. It may vary from one photoresistor to another, even of the same type, and it is probably temperature-dependent. But in terms of adjusting the actual sensitivity to some exact value. No.
A photoresistor (or light-dependent resistor) is an element whose resistance changes with the amount of light shining on it. When exposed to light, the resistance of a photoresistor decreases, and when in darkness, the resistance increases. This property makes photoresistors useful in light-sensing applications.
A light sensitive switch, also known as a photoresistor or photocell, is an electronic component that changes its resistance depending on the amount of light it is exposed to. When the light level changes, the resistance of the photoresistor changes, causing it to switch the circuit on or off. This is commonly used in applications such as street lighting, security systems, and camera exposure control.
The use of the micro- prefix for capacitance, i.e. microfarads, is common because the farad is a very large unit of capacitance and we don't normally use capacitors in that range of value.
photoresistor - resistance drops with brighter lightsolarcell - generates voltage when illuminatedphototransistor - collector current increases with brighter lightphotomultiplier - anode current increases with brighter lightetc.Or did you want the physics?
A photoresistor, light dependent resistor (LDR) or cadmium sulfide (CdS) cell is a resistor whose resistancedecreases with increasing incident light intensity. It can also be referred to as a photoconductor.Applications:camera light meters, street lights, clock radios, alarms, and outdoor clocks
Function
The parent function of the exponential function is ax
The IF function is the main function to do it and you can also use other logical functions, like the AND function, the OR function or the NOT function.
