Answer:

  b.  y = f(x/2)

Step-by-step explanation:

The transformation ...

  y = f(x/k)

represents a horizontal stretch by a factor of k.

Here, the red graph is a horizontal stretch of the black graph by a factor of 2. That is, k=2 in the above transformation.

  y = f(x/2) . . . equation of the red graph
