Understanding Functions in Algebra
A function is a relation between a set of inputs and a set of possible outputs with the property that each input is related to exactly one output. Functions are often denoted by the letters f, g, and h.
For example, in the function f(x) = x + 2, the input, x, is increased by 2 to produce the output.
Functions can be represented in many ways: through equations, graphs, tables, or verbal descriptions. They are foundational in understanding more complex mathematical concepts. 📚
