An exponential function f(x) is reflected across the x-axis to create the function g(x). Which is a true statement regarding f(x) and g(x)?

Reflecting a graph across the x-axis changes every output y to its opposite, −y. Therefore, for every input x, g(x) = −f(x), so the functions have opposite output values. The true statement is that the functions have opposite outputs for any given input.
