Functions basically establish relationships between expressions. Many common Algebraic functions are expressed as functions of x:
f(x) = x2 + 4
Which could also be written as y = x2 + 4
However, this just scratches the tip of the universe. Not only do mathematical functions vary in complexity and offer an infinite number of possibilities, there are also programming functions. Programming functions are typically groups of commands that accept one or more parameters, then return one or more pieces of information.
The above Mathematical function can be re-written as a Perl programming function that accepts a value for x:
sub calculateFunction {
my ($x) = @_;
my $y = x**2 + 4;
return ($y);
}
Y = X2 Is a parabolic function.
y = cuberoot(x) for real x is not a rational function.
No. A simple example of this is y = x2; the inverse is x = y2, which is not a function.

An example of a wrong function equation is f(x) = sqrt(x) for all non-negative x.
A function call is where you "call" a function and execute its body. For example: void example() { } int main() { example(); // call the function "example" and execute its bodyreturn 0; }
It is a Basic Statistical Function.
Y = X2 Is a parabolic function.
It is called callback function. For an example see the qsort function.
y = cuberoot(x) for real x is not a rational function.
No. A simple example of this is y = x2; the inverse is x = y2, which is not a function.
fsetpos for example.

One example of a simple Borel measurable function is the indicator function of a Borel set. This function takes the value 1 on the set and 0 outside the set, making it easy to determine its measurability with respect to the Borel sigma algebra.

explain about function call
You need to give an example of the rule and the function you want.
