Question

The graph of g(x) is obtained by reflecting the graph of f(x)=4|x| over the x-axis.

Which equation describes g(x)?

g(x)=|x+4|

g(x)=|x|−4

g(x)=−4|x|

g(x)=|x−4|

Answer 1

it's very similar to this previous problem

Answer 2

ok i think it is A

Answer 3

in `f(x)=4|x|` is the "4" positive or negative?

Answer 4

positive

Answer 5

So we flip it to negative to get `-4|x|`. Doing this will flip the entire graph over the horizontal x axis
