Question 1
What is the range of this relation?
{(-5,5).(-1,0).(3.-4).(-1,2))

hi,

3. 12.15, you are correct.

4.2.01, your first digit is correct,

hope this !

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
