Assume that you own 304 shares of General Dynamics Corp. (GD) selling at $102 per share. In order to make the stock more affordable for the average investor, GD's management has decided to split the stock. How was your investment worth prior to the stock?

given that triangle abc is transformed two times to get triangle

a"b"c"

first abc is transformed in to a'b'c' as follows:

the coordinates of a are (1,-1) and transformed into a'(-1,1)

similarly b (4,-2) became b'(-4,2) and

c(7,-2) became c'(-7,2)

i.e. (x,y) becomes (-x,-y)

this is nothing but reflection about a point here origin.

thus first transformation is reflection on the origin.

next is exactly shifting 3 units down
