Hi can someone explain what is meant by the inverse of a transformation
Algebra and Geometey -
it is the transformation needed to return to the original state.
Just as an inverse function is what you need to get x.
sqrt(x) and x^2 are inverses because (sqrt(x))^2 = sqrt(x^2) = x
similarly, stretch by 2 and shift 8 up has the inverse transformation
shift down 8 and shrink by 2.
+ is the inverse of -
and so on.
