g(x) = x²

f(x) = 2g(x -3) + 4

The 2 doubles the height of g without increasing the width, so makes f thinner than g.  The x-3 shifts g to the right.  The +4 shifts the (doubled) g up four units.

OK, let's go through the answers.

A.  f is wider.  No the 2 makes f thinner.

B. Narrower, good.  Vertex moved right 3 and up 4.  Sounds right

Answer: B

Let's check the others.

C. Narrower, ok.  Left four units, nope.

D.  Wider, nope.
