Question

A transformation named t maps triangle xyz to triangle x'y'z' the image of y is ?

Answer 1

y'

The way the transformation is written tells which point goes where; the first point x is mapped to point x', y goes to y', z goes to z'.

Answer 2

A transformation named t maps triangle xyz to triangle x'y'z' the image of y is:

y'

Explanation:

We are asked to find the image of y given that:

a transformation named t maps triangle xyz to triangle x'y'z'.

Hence, the image of y is y'.

Since we know that if any triangle xyz is transformed to x'y'z' then the vertices of the triangle x is transformed to x' , y is transformed to y' and z is transformed to z'.

i.e. x → x'

y → y'

and z → z'

Hence, A transformation named t maps triangle xyz to triangle x'y'z' the image of y is:

y'
