Can a function have different outputs?
No mathematical function has “multiple outputs for a single input”. Many mathematical functions have more than one input that gives the same output.
Can a function have different inputs but the same output?
Each input has only one output. Each input has only one output, and the fact that it is the same output (4) does not matter. This relation is a function. Remember that in a function, the input value must have one and only one value for the output….
| x | y |
|---|---|
| −5 | −6 |
| −2 | −1 |
| −1 | 0 |
| 0 | 3 |
Can a function only have one input?
A function is a kind of rule that, for one input, it gives you one output. An example of this would be y=x2. If you put in anything for x, you get one output for y.
Can a function be called from more than one place within a program justify your answer in brief?
The same function can be accessed from several different places within a program. Thus, the argument names in a function definition need not be the same as those used in the segments of the program from which the function was called. However, the corresponding data types of the arguments must always match.
Why can a function 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.
Is it possible that a function have more?
Answer: True, A function may have any number of return statements each returning different values and each return statements will not occur successively.
Why function has only one output?
Do all functions have an inverse?
A function has an inverse if and only if it is a one-to-one function. That is, for every element of the range there is exactly one corresponding element in the domain. To use an example f(x), f(x) is one-to-one if and only if for every value of f(x) there is exactly one value of x that gives that value.
Why can functions only have one output?
How many outputs are there for each input in a function?
one output
A function is a relation between sets where for each input, there is exactly one output.
Is it possible that a function have more than one return statements true and false?
A function may have any number of return statements each returning different values. Explanation: True, A function may have any number of return statements each returning different values and each return statements will not occur successively.
Can you call a function more than once?
Yes any function (user-defined or from a library) can be called any number of times from any function including itself(in case of user-defined, called recursion) except for the main function. But a function can only be defined once. Absolutely, except for main, which cannot be called.
How do you get the mean of a function with multiple outputs?
Function with Multiple Outputs. Define a function in a file named stat.m that returns the mean and standard deviation of an input vector. function [m,s] = stat(x) n = length(x); m = sum(x)/n; s = sqrt(sum((x-m).^2/n)); end.
Can a deterministic function give the same output for every input?
A stateful deterministicfunction may not give the same output for every input. Example: F(x)is defined to return trueif it’s called with the same argument as the previous call. Clearly with the sequence {1,2,2} => {undefined, false, true}this is deterministic, yet it gives different outputs for F(2). – MSalters May 2 ’16 at 10:44
How do you write multiple functions in a function file?
Multiple Functions in a Function File Define two functions in a file named stat2.m , where the first function calls the second. function [m,s] = stat2(x) n = length(x); m = avg(x,n); s = sqrt(sum((x-m).^2/n)); end function m = avg(x,n) m = sum(x)/n; end
Can a function be considered pure?
Only depends on its input. That is, given the same input, it will always return the same output. Is referentially transparent: the function can be freely replaced by its value and the “behavior” of the program will not change. With this definition, it’s clear your second function cannot be considered pure, since it breaks rule 2.
