whats a function notation

Answer 1

Function notation is a way to represent a function mathematically. It is commonly used to denote the independent and dependent variables in a function.

In function notation, the function is typically represented by a letter, such as f(x), g(x), or h(x). The letter before the parentheses represents the name of the function, while the variable inside the parentheses (in this case, x) represents the input or independent variable.

For example, if we have a function that doubles the input, we can represent it using function notation as f(x) = 2x. In this case, f(x) is the name of the function, and x is the input.

Function notation can also be used to specify the output or dependent variable. For example, if we have a function that multiplies the input by 3 and adds 5, we can represent it using function notation as g(x) = 3x + 5. In this case, g(x) is the name of the function, and the expression 3x + 5 represents the output or dependent variable.
