function notation
Another name for y denoted as f(x) and read as the value of f at x or f of x
Function notation is a way of representing a mathematical function using symbols and variables. The standard notation for a function is f(x), where f is the name of the function and x is the independent variable, usually representing the input values. The function itself is defined as a mathematical relationship between the input variable and the output variable, which is usually denoted by f(x).
For instance, suppose we have a function that takes an input number, adds two to it, and then multiplies the result by three. In function notation, we could write this as:
f(x) = 3(x + 2)
Here, the name of the function is f, and the independent variable is x. The expression x + 2 represents the input value, which is then multiplied by 3 to get the output of the function.
We can use function notation to evaluate the function for specific input values by substituting the value of x into the function. For example, if we want to evaluate the function f(x) at x = 3, we can replace x in the equation with 3:
f(3) = 3(3 + 2) = 15
This tells us that the output of the function for an input value of 3 is 15.
Function notation is widely used in mathematics, physics, engineering, and other sciences to represent mathematical relationships and to perform calculations.
