What transformation occurs when a function f(x) is transformed to g(x) = 2f(x)?

• A vertical stretch by a factor of 2.

• A horizontal stretch by a factor of 2.

• A vertical compression by a factor of 1/2.

• A horizontal compression by a factor of 1/2.

How does the graph of g(x) = f(2x) relate to the graph of f(x)?
