Mathematical functions

Mathematical functions are like machines that take an input, perform a specific operation, and produce an output. Each input has a unique output determined by the function’s rule. For example, a function might add 3 to any number you give it. Functions help us describe relationships between quantities precisely, whether in everyday scenarios or science. They’re fundamental in understanding patterns, solving problems, and modeling real-world situations efficiently. Think of a function as a consistent process that transforms inputs into outputs based on a set rule, providing a clear and reliable way to relate different quantities.
