That means that function "g" is first applied to the number 4. Then, the result of that is used with function "f".
A Function. That is the definition of a function. I like to think of a function, f(x) as a number crunching machine. the number crunching machine eats different x 's. It eats each and every x and crunches it the same way, but spits out a new Y every time. Remember, y = f(x). That is, "y is a function of x". There you go.
A function is a mapping from one set of numbers (domain) to another (range). The mapping need not be linear: it can be any mathematical function. That is, for every number in the domain the function provides a rule which allows you to calculate another number.If, then, you devise another function which is a mapping from the range of the first function to some other set, you have a function of a function.For example, suppose the first function, f, is "add 1" and the second function, g, is "square the number."Then the functiong of f = g[f(x)] = g[x+1] = [x+1]2 = x2 + 2x + 1however, note thatf of g = f[g(x)] = f[x2] = x2 + 1This illustrates that f of g is not the same as g of f.
A recursive function is one in which the value of a function at each point depends on its value at one or more previous points. A rercursive function requires the first few values to be defined normally - these are called bases. Perhaps one of the most famous recursive function is the Fibonacci series, which has f(1) = 1 f(2) = 1 f(n) = f(n-1) + f(n-2) for n = 3, 4, 5, ... There are two bases and each subsequent value is defined in terms of the preceding two.
I assume the question is about the range of a function f. First, determine the domain of the function f. This is the set of all inputs. Use this information to find all the output values of f: that is the range. In most cases, you will not have to evaluate f for each and every input: the nature of f will help you.
Function Keys
The F Lock on a keyboard disables the use of function keys. E.G: F1 F2 F3 etc.
Most keyboards have 12 function keys. F1-F12 (all the keys with the letter 'F' and then a number).
The rule that determines the output number based on the input number is known as a function. For example take the function: f(x) = x+1. F is the name of our function, x is the input number, and f(x) is our output number. So if our input number is 3, our function or "rule" says to add one to it. Therefore, f(x), known as the output number, would be 4 since 3+1 = 4.
Keyboard shortcuts are controlled in System Preferences/Keyboard. Apple has preselcted some keys such as F10, F11, and F12 to control volume. These keys can be set to other functions in the System Preferences/Keyboard pref pane. There are many function available. Take care in setting them so that you don't have two keys doing the same function. To use the F keys as function keys and not as the preset keys, press the fn key on the keyboard first, and then press the F# key you need.
That means that function "g" is first applied to the number 4. Then, the result of that is used with function "f".
f(x)=5x Domain is any number for x that will provide a real number for f(x). In this function, x can be any real number, and f(x) will be a real number. Thus domain is all real numbers.

It's one of the "F" keys. I think it's F-3? You may have to go into the control panels in Keyboard option to set the F-keys to Function keys.
The f key on a keyboard is located between the d and g keys.
The keyboard notes for the Mission Impossible theme tune begin with F F F F F F A B F F F F F F E E. The remaining keyboard notes can be purchased for a small fee from the Music Notes website.
A function, in mathematics, associates one quantity, the argument of the function, also known as the input, with another quantity, the value of the function, also known as the output. A function assigns exactly one output to each input. The argument and the value may be real numbers, but they can also be elements from any given set. An example of a function is f(x) = 2x, a function which associates with every number the number twice as large. Thus 5 is associated with 10, and this is written f(5) = 10.
