Which graph is the result of reflecting f(x) = (8)x across the y-axis and then across the x-axis?

Refrection of a function across the y-axis, changes the sign of x in the function.

Thus, given the function:

Refrection of the function across the y-axis will result in the function:


Refrecting a function across the x-axis, changes the sign of the function.

Thus, refrecting the function:

across the x-axis will result in the function:


The graph of and is attached.
The green curve represents the graph of the function , while the orange curve represents the graph of the function .
