Answer:
The transformation from f to g represents a Vertical stretch.
Explanation:
We are given a parent function f(x) as:

and the transformed function g(x) as:

We know that any function transformation of the type:
f(x) → a f(x)
represents either a vertical stretch stretch or compression depending on the value of a.
If 0<a<1 then the transformation is a vertical compression and if a>1 then the transformation is a vertical stretch.
Here we have a=6>1
Hence, the transformation is a VERTICAL STRETCH.
