Each input has only one output
. … Remember that in a function, the input value must have one and only one value for the output. Domain and Range. There is a name for the set of input values and another name for the set of output values for a function.
Can a function have multiple inputs that give the same output?
Short answer:
Yes
. Long answer: Yes, but using the Cartesian product, you can consider multiple inputs as being a single input, where the single input is an ordered pair.
Can two outputs be the same in a function?
you cannot be two places at the same time
,
A function is a relation between sets where for each input, there is exactly one output.
| x y | −5 −6 | −2 −1 | −1 0 | 0 3 |
|---|
What has one input but many outputs?
De-multiplexer
is also a device with one input and multiple output lines.
What is function input and output?
In mathematics, a function is any expression that produces exactly one answer for any given number that you give it.
The input is the number you feed into the expression
, and the output is what you get after the look-up work or calculations are finished.
What is the test that you can do to tell if a graph represents a function?
The vertical line test
can be used to determine whether a graph represents a function. If we can draw any vertical line that intersects a graph more than once, then the graph does not define a function because a function has only one output value for each input value.
What is not a function?
A function is a relation in which each input has only one output. …
x
is not a function of y, because the input y = 3 has multiple outputs: x = 1 and x = 2. Examples: : y is a function of x, x is a function of y. : y is not a function of x (x = 3 has multiple outputs), x is a function of y.
Can a function have two outputs Python?
Python functions can return multiple variables
. These variables can be stored in variables directly. A function is not required to return a variable, it can return zero, one, two or more variables. This is a unique property of Python, other programming languages such as C++ or Java do not support this by default.
Why do functions only have one output?
In a function every input number is associated with exactly one output number In a relation an input number may be associated with multiple or no output numbers. This is an important fact about functions that cannot be stressed enough:
every possible input to the function
must have one and only one output.
How do the phrases in the input and output differ?
An input device sends
information
to a computer system for processing, and an output device reproduces or displays the results of that processing. Input devices only allow for input of data to a computer and output devices only receive the output of data from another device.
What has one input and several output lines?
A Demultiplexer or Demux
is a device that takes a single input line and routes it to one of several digital output lines. It is a process of taking information from one input and transmitting over one of many outputs. It is the opposite of multiplexer.
What is the input for an 8 to 1 multiplexer circuit?
An 8-to-1 multiplexer consists of
eight data inputs D0 through D7, three input select lines S0 through S2 and a single output line Y
. Depending on the select lines combinations, multiplexer selects the inputs.
Is a circuit with one input and many outputs?
Demultiplexer
means one to many. A demultiplexer is a circuit with one input and many outputs. By applying control signal, we can steer any input to the output.
What is the output when the input is 2?
When we input 2 into the function g, our output is
6
. When we input 4 into the function g, our output is also 6.
