Let assume that the $X = [x_1,1,x_1,2]times[x_2,1,x_3,2]times[x_3,1,x_3,2]times[x_4,1,x_4,2]$, $Y=[y_1,1,y_1,2]$ where $x_n,m $ and $ y_n,m$ are real numbers for all $n,m$.



Show that $f: X to Y $ is Borel measurable function if $f$ is continuous.



I think the domain of the function $f$ is a Borel set because the $X$ is a cartesian product of Borel sets, Cartesian Product of Borel Sets is Borel Again.



And I know that continuous functions are measurable w.r.t. Borel sigma-algebra. But I want to clear proof for the problem.
