Determine if the triangles are similar if similar state how and complete the similarity statement PLS HELP

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

Which composition of similarity transformations maps polygon abcd to polygon a'b'c'd'? a dilation with a scale factor less than 1 and then a reflection a dilation with a scale factor less than 1 and then a translation a dilation with a scale factor greater than 1 and then a reflection a dilation with a scale factor greater than 1 and then a translation

How do i do this activity, is appreciated
