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 retarder shouldn't be using an automobile in the first place
no it do not answer my question
No, you should not turn off the retarder when the road is wet or snow covered because the retarder helps to slow down the vehicle without relying solely on the brakes. Keeping the retarder on can help maintain control and stability in slippery conditions.
No
It slows down the drying time

Are you talking about the Jake Brake on semis?
Usually busses do not have retarders because they are too loud and cannot be used inside most city limits on a semi truck they have a switch to turn on the jake brake (engine brake, or retarder) when the switch is on and you let the accelerator all the way up the brake takes over. All a retarder does is use your air brakes (or hydraulic) less to prevent overheating that will lead to brake loss.
Something that slows the progress of something else. An impediment would be a better word to use.
Yes, trisodium citrate can be used as a cement retarder. It works by delaying the hydration process of cement, which slows down the setting time. Trisodium citrate is often preferred for its ability to control the setting time of cement mixes effectively.
Steep downgrades, when you need it to control your descent.
retarder increases time to set, accelerator decreases setting time
