Question

Given f (x )=|x|. Describe the transformations performed on the graph of f (x) to get

g (x)=3 |x| + 4.
A. The graph of f(x) is translated to the left 4 units and dilated by a factor of 1/3.
B. The graph of f(x) is translated up 4 units and dilated by a factor of 3.
C. The graph of f(x) is translated to the right 4 units and dilated by a factor of 3.
D. The graph of f(x) is translated up 4 units and dilated by a factor of 1/3.

Answer 1

Answer: B

Explanation:

The +4 represents the variable “k” which controls whether the vertex of the graph goes upwards or downwards
