2,4,6,7
Step-by-step explanation:
can't have the same x value in a function
$9.20, divided 45 by 5 you get 9.2 since this is money you add a 0
ANSWER
D. a vertical translation of f(x) four units downward
EXPLANATION
The given function are:
f(x)=|x|
and
g(x)=|x|-4.
We can rewrite g(x) in terms of f(x) to obtain:
g(x)=f(x)-4.
This means that, if the graph of f(x) is translated 4 units down, we obtain the graph of g(x).
Hence g(x) is a vertical translation of f(x) four units downward.
The correct choice is D.
