Inverse functions are like doing things backwards.

Imagine you have a function, which is like a recipe.

When you have something like ( f(x) = 2x + 3 ), the inverse function is what you get when you switch things up.

For this example, the inverse is ( f^{-1}(x) = \frac{x - 3}{2} ).

Real-World Uses:

1. Money Matters: Inverse functions can help you figure out how much money you had before you added interest.
2. Science: In physics, if you want to find speed, you can use the inverse of the relationship between distance and time.

By understanding inverse functions, you can tackle everyday problems much easier!
