On b. It says 1/2y and then it said a vertical compression of 2.

#

But on c it says 1/3y but then it says a vertical EXPANSION of 3.

#

This confuses me

#

#

It should be a vertical expansion/stretch for both of them since it’s always cf(x) where c is (1/c)y when you switch it to the other side no?
