Describe the change in the graph of the parabola f(x) when it transforms into g(x) = −3f(x).

The parabola g(x) will open in the opposite direction of f(x), and the parabola will be narrower than f(x).
The parabola g(x) will open in the same direction of f(x), and the parabola will be narrower than f(x).

Answer:

  A: opposite direction, narrower

Step-by-step explanation:

The multiplier -3 will cause the parabola to be scaled vertically by a factor of 3, causing it to appear narrower than the original. The fact that this multiplier is negative means the function will be reflected across the x-axis, making it open in the opposite direction.

An example is shown in the attachment.
