The video tutorial explains the transformation of the function f(x) into g(x) by flipping it over the x-axis and diminishing it by a factor of 1/3. The instructor uses visual aids and specific values to verify the transformation, concluding that g(x) is equal to negative 1/3 of f(x). Despite this not being one of the given choices, the instructor confidently supports this conclusion with examples.

What is the main task described in the video regarding the functions f(x) and g(x)?

• To find the intersection points of f(x) and g(x).

• To determine g(x) as a transformation of f(x).

• To calculate the area under the curve of f(x).

• To find the derivative of g(x).

What initial transformation does g(x) appear to undergo compared to f(x)?

• A rotation around the origin.

• A flip over the x-axis.

• A horizontal shift to the right.

• A vertical stretch.

What additional transformation is suggested for g(x) after flipping f(x) over the x-axis?

• A vertical stretch by a factor of 3.

• A vertical compression by a factor of 1/3.
