Which statement best describes how the graph of g is a transformation of the graph of f?

Question

g(x) = 4f(x)

-The graph of g is a horizontal stretch of the graph of f by a factor of 1/4
-The graph of g is a horizontal stretch of the graph of f by a factor of 4
-The graph of g is a vertical stretch of the graph of f by a factor of 4
-The graph of g is a vertical stretch of the graph of f by a factor of 1/4

Answer 1

The 4 is in front of the f(x) which makes it vertical stretch.

My answer is:
The graph of g is a vertical stretch of the graph of f by a factor of 4

Am I right or wrong sir?

Answer 2

correct
