Explanation:
since T and F traded places (top and bottom vertex) in the operation, the first step was then a reflection over the x-axis.
the result was then translated (shifted) to the right by 17 units. that changed the x-coordinate of e.g. W from -3 to 14.
finally, that result was then translated up by 5 units changing the y-coordinate of e.g. W from 0 to +5.
