The functions f(x) = −x + 3 and g(x) are shown in the graph. The function g(x) is a transformation of f(x), such that g(x) = kf(x), where k is a rational number.

Graph of linear function f of x going through negative 1 comma 4, 0 comma 3, and 1 comma 2 and linear function g of x going through negative 1 comma 8, 0 comma 6, and 1 comma 4. The functions intersect at 3 comma 0.

Which of the following statements describes the effect and value of k?

a
The graph of g(x) is a vertical stretch of the graph of f(x); the k value is positive and greater than 1.

b
The graph of g(x) is a vertical compression of the graph of f(x); the k value is positive and less than 1.

c
The graph of g(x) is a vertical stretch of the graph of f(x); the k value is positive and less than 1.

d
The graph of g(x) is a vertical compression of the graph of f(x); the k value is positive and greater than 1.
