Theorem
Let $a \in \R_{>0}$.
Rational Power
Let $f: \Q \to \R$ be the real-valued function defined as:
- $\map f x = a^x$
where $a^x$ denotes $a$ to the power of $x$.
Then $f$ is continuous.
Real Power
Let $f : \R \to \R$ be the real function defined as:
- $\map f x = a^x$
where $a^x$ denotes $a$ to the power of $x$.
Then $f$ is continuous.
