The function of the image of function y = 2 ^ x with respect to the image of x-axis symmetry is

The function of the image of function y = 2 ^ x with respect to the image of x-axis symmetry is

Let the symmetric function be: F (x)
For X-axis symmetry, then there is:
f(x)=-y
--> f(x)=-2^x
I hope I can help you
