Question

The graph of g(x) is obtained by reflecting the graph of f(x)=−3|x| over the x-axis.
Which equation describes g(x))?

g(x)=|x+3|

g(x)=−|x+3|

g(x)=−3|x|

g(x)=3|x|

Answer 3

hint:
reflection about the x-axis:
\(s_{y=0}: f(x) -> -f(x)\) i.e. reflection about the x-axis.

Answer 4

ok @mathmate dose that mean C

Answer 5

what @mathmate is saying is that you change the outer-most sign from positive to negative

For example: y = 10x would turn into y = -10x. We've gone from positive 10 to negative 10

Another example: y = -5x^2 would turn into y = 5x^2. Now we've gone from negative 5 to positive 5.
