It is 4.
Anything you like - it depends on the function that relates the output to the input.
The output is tripled.
You how to remember input and output is like a machine do the rest.
It is a bijective function.
A function is a rule which assigns exactly one output f(x) to every input x.
Anything you like - it depends on the function that relates the output to the input.
The rule of a function in math is what relates the input value to the output value. For example, if f(x) = x2, the "function rule" is to square the input value to get the output value.
The value that results from the substitution of a given input into an expression or function is the output. The value substituted into an expression or function is an input.
Anything you like - it depends on the function that relates the output to the input.
Suppose a function takes values of a variable, X, as its input, and that it converts it into an output value Y.Then the graph of the function, in the X-Y coordinate plane, is the set of all points (x, y) such that when you input the value x into the function, the output is y.Suppose a function takes values of a variable, X, as its input, and that it converts it into an output value Y.Then the graph of the function, in the X-Y coordinate plane, is the set of all points (x, y) such that when you input the value x into the function, the output is y.Suppose a function takes values of a variable, X, as its input, and that it converts it into an output value Y.Then the graph of the function, in the X-Y coordinate plane, is the set of all points (x, y) such that when you input the value x into the function, the output is y.Suppose a function takes values of a variable, X, as its input, and that it converts it into an output value Y.Then the graph of the function, in the X-Y coordinate plane, is the set of all points (x, y) such that when you input the value x into the function, the output is y.

The output is multiplied by 5.
The output is multiplied by 5.
The output is multiplied by 3.
The rule is what actions (operations) the function performs. The only requirement is that for each imput there is an output and that the same input always results in the same output. (Different inputs can have the same output).
The output is three times as large.
