If you shift the linear parent function, f(x)=x, up 13 units, what is the equation of the new function?

(mc 02.03) what set of reflections and rotations would carry rectangle abcd onto itself? reflect over the y-axis, reflect over the x-axis, rotate 180° rotate 180°, reflect over the x-axis, reflect over the line y=x reflect over the x-axis, rotate 180°, reflect over the x-axis rotate 180, reflect over the y-axis, reflect over the line y=x

I'm confused on this could anyone me and show me what i need to do to solve it.
