find g(x), where g(x) is the reflection across the x-axis of f(x) = x? .

Step-by-step explanation:

The reflection of a function along the is given by .

Here the given function is . Therefore the reflection would be .

To find reflection draw the graph of it and think about how the graph of its mirror image would be. You would arrive at the reflection function.

the two may have that, even a breakdown is probably offered
