Question

Which of the following correctly identifies the transformations undergone from f(x)=x
to f(3x)−1/3 =3x−1/3
(1 point)

compressed horizontally and shifted down

reflected over the y-axis and shifted up

stretched horizontally and shifted down

reflected over the x-axis and shifted up

Answer 1

Compressed horizontally and shifted down.

Reason: f(3x) replaces x by 3x, which is a horizontal compression (x-values scaled by 1/3). Subtracting 1/3 shifts the graph down by 1/3.
