A reflection over the y axis

A translation of 1 unit down

A reflection over the x axis

A translation of 1 unit up



(If your not sure , please don’t answer)

Answer 1

A reflection over the y axis .

Explanation:

Given : Transforms (a,b) to (-a,b).

To find : What type of transformation.

Solution : We have given

Parent function : (a,b) .

Transformed : (-a ,b).

Transformation rule of reflection over y axis : ( x, y) →→ ( -x ,y).

Then we can say in transformation (a,b) →→→→ (-a,b).

Therefore, A reflection over the y axis .
