# Antiderivative

A function whose derivative is the initial function is called **antiderivative**. These are obtained by integration.

!

### Remember

A function $F$ is the

**antiderivative**of $f$, if $F'(x)=f(x)$i

### Hint

The initial function is obtained by taking the derivative of the antiderivative.

Put simply, the antiderivative is the function from which the initial function is "derived".

Put simply, the antiderivative is the function from which the initial function is "derived".

- $f'(x)$ is the derivative of $f(x)$
- $f(x)$ is the antiderivative of $f'(x)$
- $F(x)$ is the antiderivative of $f(x)$
