Let S ⊆ R and let G be an arbitrary isometry of R . Prove that
the symmetry group of G(S) is isomorphic to the symmetry group of
S. Hint: If F is a symmetry of S, what is the corresponding
symmetry of G(S)?
I

I want to:
1) create a plot of the birth weight vs the gestational age
and I want to colour code the points based on the mothers smoking
status to determine whether or not smoking affects the
