Are we supposed to guess???
yw good luck
i did the three questions then i put some math notes in the bottom right corner
a) Corresponding angles of similar figures are congruent, so 
b) Scale factor = (image)/(preimage). Since we are looking for ABCD to WZYX, this means that WZYX is the image and ABCD is the preimage. Thus, the scale factor is 
c) Since the scale factor is 5/2,

It is not symmetric because it has a peak at 1 and to be symmetric it has to be the same on both sides of the peak
Answer:
no, the have a negative difference
