as the number of
Yes, because the number of x-values is the
-values
No, because two points with the same y-value have different x-values
No, because two points with the same x-value have different values
Yes, because every x and value is positive

I think it is the first one.

Step-by-step explanation:

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

1 is c

2 is a

3 is a
