This type of relation is called a function (a simpler way to remember it is only one Y value for every X value).
In functions where there are turning points (local maxima or minima), different x-values will map onto the same y-value. However, if each x-value has exactly one y-value, then the function will either be increasing for all x ordecreasing for all x.
Such functions are called monotonic functions.
A signal is bounded if there is a finite value such that the signal magnitude never exceeds , that is for discrete-time signals, or for continuous-time signal (Source:Wikipedia)
This normally refers to continuity as a property of certain functions (mappings). They are called continuous if the output depends in a certain way on the input in that a small alteration in the input only leads to a small alteration in the output. Continuous functions can intuitively be drawn with a pencil without ever stopping and beginning again. More formally, a map between two topological spaces is continuous if the preimage of every open set in the codomain is an open set in the domain.
Efficiency is the ratio of power output to power input. It is not the ratio of forces or distances. You can move a load using less force by reducing the gradient of the plane. But what you gain in reduced force you lose in having to travel a greater distance to raise the load through the same height. There is, therefore, no net advantage. The only way to increase the efficiency is to reduce the friction. This can be done by lubricating the plane, or load (or both), or by placing rollers between the load and the plane - so that there is rolling friction rather than sliding friction.
A linear graph is a graph in the form of a straight line which extends unbroken in opposite directions. It can be modeled by the equation y=mx+b in which y (or f(x) as it's commonly called) is the line, m is the slope (rise/run) of the line, x is a value which you substitute into the equation for an output of y (that's how you fine the points of a line, an input of x and an output of y for the point (x,y)), and b is your y-intercept (the value of y if x=o, also where the line crosses the y-axis. Every line will have a y-intercept unless it's undefined (ex: x=6 produces a straight vertical line which crosses the x-axis as 6. every point for the line x=6 has 6 as an x value so they look like (6,y).))If you are asking the reason for B contrary to a different variable, I'm sorry to say I don't have an answer for that nor do I know if there is an answer. It might be one of those things with a "just because" answer.-skerr7464
A 360 degree survey involves a method of gaining feedback from a variety of people about an individual's performance and can be a highly powerful input to performance management and employee development.
A Function
function
A one-to-one or injective function.
The relationship is called a surjection or a surjective function.
A function is any relationship between inputs and outputs in which each input leads to exactly one output. It is possible for a function to have more than one input that yields the same output.
There need not be any relationship.
For a relationship to be considered a function, each input value must correspond to exactly one output value. This means that each input cannot have multiple outputs.
The relationship between work input and work output is defined by the efficiency of a system. Efficiency is a measure of how well a system converts input work into output work and is calculated as the ratio of output work to input work. A higher efficiency indicates a more effective conversion of work input to work output.
A function.
A function is a rule which assigns exactly one output f(x) to every input x.
a function
It is a injective relationship. However, it need not be surjective and so will not be bijective. It will, therefore, not define an invertible function.
