Which of the following statements is true of the graphs of the functions:

$$ f(x)=3{ (x-2) }^{ 2 }+4 $$

...and:

$$ g(x)= 2{ (x+1) }^{ 2 }+4 $$

A

$f(x)$ and $g(x)$ both open downward.

B

The vertex of $g(x)$ is 3 units to the right of the vertex of $f(x)$.

C

The vertex of $ f(x)$ is 3 units above the vertex of $g(x)$.

D

$g(x)$ is "narrower" than $f(x)$.

E

The vertex of $g(x)$ is 3 units to the left of the vertex of $f(x)$.
