Functions and Expressions are representations of relationships that exist among entities, however a function always returns a value (or result)
That means that function "g" is first applied to the number 4. Then, the result of that is used with function "f".
No. A function takes in values of no, one, or more input variables, and returns no or one result. It cannot return more than one result. Do not confuse this with returning multiple results using call by reference parameters - this is not the same thing.
Any number that produces an undefined result from a function f(x) is not in its domain.For example, the number 0 is not in the domain of f(x) = 1/x, because 1/0 is undefined.Undefined answers will result from any of the following situations:- Dividing by 0- Taking the square root of a negative number- Taking the log (any base) of 0 or any negative number- Taking the log (base 1) of any number
To find the square root in C, you can use the sqrt function from the math.h library. Here’s a simple program: #include <stdio.h> #include <math.h> int main() { double number, result; printf("Enter a number: "); scanf("%lf", &number); result = sqrt(number); printf("Square root of %.2lf is %.2lf\n", number, result); return 0; } This program prompts the user for a number, calculates its square root, and prints the result. Make sure to link the math library when compiling with -lm.
IF
The AND function.
Both A function and a Sub carry out a procedure, but only A function returns a result while a Sub does not return a result.
looks up a value and returns a related result from the lookup table.

The SUBTOTAL function does not insert a row. It returns the result in the cell where you type the formula. See related links for information about the SUBTOTAL function.
ROUND is a function that returns a number rounded to a specified number of digits.Syntax: =ROUND( number, digits )number is the number to rounddigits is the number of digits to round the number toEXAMPLES:=ROUND(1/3,2) will return 0.33=ROUND(1/6,2) will return 0.17
The MAX function returns the largest number from the cells you evaluate.EXAMPLE:A1 = 104A2 = 623A3 = 23A4 = 234A5 = 198FORMULA: =MAX(A1,A2,A3, A4, A5) will display a result of 623, because A2 contains the largest number.
The AVERAGE function.
The return statement is used in functions to return control to the caller. If the function is declared non-void, the return statement also allows the programmer to return a value to the caller.
The coalesce function returns the first expression that contains the highest in data precedence. If all other expressions are considered 'nonnullable, then the result will be labelled nonnullable as well.
