Graph reflected in the x-axis problem?

Question

If the graph of y = 2^-x - 1 is reflected in the x-axis, then what would the equation of the reflection be?

Answer 1

Change y to - y

=> y = 1 - 2^-x

Answer 2

y= - 2^(-x) +1

Answer 3

Reflecting cos x around the x-axis motives a one hundred eighty degree section shift. in any different case, it ameliorations no longer something. Translating the mirrored photograph up one unit motives one to be extra to everyy factor of the mirrored photograph, so as that the max value is now 2 and the min value is now 0. The amplitude and the era proceed to be a similar. to regulate the amplitude you're able to ought to multiply cos x by using some type which contain 10. to regulate the era you're able to ought to multiply x by using some consistent. Neither of those issues advance into executed by using the mirrored photograph and the translation.
