Respuesta :
g(x) = |x| − 4 is obtained from f(x) = |x| by applying a vertical transformation of f(x) four units downwards.
Answer:
The correct option is D. A vertical transformation of f(x) four units downward
Step-by-step explanation:
The function f(x) = |x| and the function g(x) = |x| - 4
A). A vertical transformation of f(x) four units upward :
f(x) = f(x) + 4
⇒ f(x) = |x| + 4 ≠ g(x)
B). A horizontal transformation of f(x) four units to the left
f(x) = f(x + 4)
⇒ f(x) = |x + 4| ≠ g(x)
C). A horizontal transformation of f(x) four units to the right
f(x) = f(x - 4)
⇒ f(x) = |x - 4| ≠ g(x)
D). A vertical transformation of f(x) four units downward
f(x) = f(x) - 4
⇒ f(x) = |x| - 4 = g(x)
Therefore, The correct option is D. A vertical transformation of f(x) four units downward
