An equation to find the value of the variable 104, 137, 154 and x with a mean of 130 is: (104 + 137 + 154 + x)/4 = 130 395 + x = 130 * 4 x = 145.
Write each equations in popular form. ... Make the coefficients of one variable opposites. ... Add the equations ensuing from Step two to remove one variable. Solve for the last variable. Substitute the answer from Step four into one of the unique equations.
mean(5.2 + 8.3 + 8.5 + 7.7 + 7.8 + y) = 7.1=> y = 5.1
Suppose a function f(.) is defined in the following way: f(1) = 3 f(2) = 10 f(3) = 1 We could write this function as the set { (1,3), (2, 10), (3,1) }. The inverse of f(.), let me call it g(.) can be given by: g(3) = 1 g(10) = 2 g(1) = 3
First, this function is strictly increasing on the entire real line, so an inverse exist on the entire real line. We define inverse of function f, denoted f^-1 such that if y = f(x) then f^-1(y) = x Or to find the inverse, all is needed is to isolate x in terms of y. In this case, y = 7x + 2 7x = y - 2 x = (y - 2)/7 So the inverse is x = (y - 2)/7 What? You don't like function in terms of y? Well, they are just meaningless variables anyway, you can write whatever, in particular the inverse is y = (x - 2) / 7 (the x, y here are independent with the x, y above. If you are getting confused, write b = (a - 2)/7 where b is a function of a)

Functions are used to reduce the lines of code and the complexity of the code. For an instance let us suppose that you want to calculate the factorial of numbers at different times in a program. There are two ways to do this 1. Write a 4-5 line code every time you want to calculate factorial. 2. Write a function of 4-5 lines which calculates the factorial and call that function every time you need to calculate factorial by just writing a single line. In C++ you can pass the variable, address of the variable or a reference to the variable in a function
When defining your function, do not put any arguments in the definition (e.g. function myFuntion()). Inside the function, you can use func_num_args() and func_get_arg($number) to get the function's arguments.
A function is any rule to assign a value (for example) to a variable "y", depending on the value of variable "x". Such a rule can be written in different ways; in algebra, it is common to write some equation, preferably one that is already solved for "y", such as: y = x2 + 3
A variable is usually used for that - for example, a single letter that represents the unknown quantity.
The dependent variable, y, is equal to 7 less than twice the independent variable, x.
1) Solve the equation for the desired variable. 2) Write it in function notation. For example, if y = 2x + 3, it is already solved for "y"; just rewrite it as f(x) = 2x + 3.
Register variables are stored in register of microprocessor/micro-controller. The read/write access to register variable is the fastest because CPU never need any memory BUS operation to access these variable. Auto variable are stored in stack thus access are much slower. Auto variable can be converted to register by using register keyword before it. It has platform specific limitation. Register variable will work only if free registers are available to hold the variable for a function scope. In case of Microprocessor or microcontrollers having very less number of general purpose registers will never take register variable even if we declare it as register.
Here is a example. "I wrote variable in a sentence."
Yes, if you write something that way, it usually refers to a function. v(x) means that you have a function called "v", and that it somehow depends on a variable called "x".
There are several methods, all leading to a similar place. The first is to simply declare a function using the function keyword: function ourFunction(args){} The second is to assign a variable as a function: var ourFunction = function(args) {}; And the third (commonly used in JavaScript frameworks, or when function is being passed as a parameter) is to just use an anonymous function. window.onload = function(args) {};
