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

Thus, given the function:

f(x)=(8)^x
Refrection of the function across the y-axis will result in the function:

g(x)=(8)^(-x)

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

Thus, refrecting the function:

g(x)=(8)^(-x)
across the x-axis will result in the function:

h(x)=-(8)^(-x)

The graph of
f(x)=(8)^x and
h(x)=-(8)^(-x) is attached.
The green curve represents the graph of the function
f(x)=(8)^x, while the orange curve represents the graph of the function
h(x)=-(8)^(-x).
