+**Theorem:** Let $X$ be a random variable following a continuous uniform distribution:
+
+$$ \label{eq:cuni}
+X \sim \mathcal{U}(a, b) \; .
+$$
+
+Then, the quantile function of $X$ is
+
+$$ \label{eq:cuni-qf}
+Q_X(p) = bp + a(1-p) \; .
+$$
+
+
+**Proof:** The [cumulative distribution function of the continuous uniform distribution](/P/cuni-cdf.html) is:
+
+$$ \label{eq:cuni-cdf}
+F_X(x) =
+\begin{cases}
+\;\; 0 & , \text{if} \; x < a \\
+\frac{x-a}{b-a} & , \text{if} \; a \leq x \leq b \\
+\;\; 1 & , \text{if} \; x > b \; .
+\end{cases}
+$$
+
+Thus, the [quantile function](/D/qf.html) is:
+
+$$ \label{eq:cuni-qf-s1}
+Q_X(p) = F_X^{-1}(x) \; .
+$$
+
+This can be derived by rearranging equation \eqref{eq:cuni-cdf}:
+
+$$ \label{eq:cuni-cdf-s2}
+\begin{split}
+p &= \frac{x-a}{b-a} \\
+x &= p(b-a) + a \\
+x &= bp + a(1-p) = Q_X(p) \; .
+\end{split}
+$$
