Question

Which function represents g(x), a reflection of f(x) = 1/2(3)^x across the y-axis

Answer 1

They both have to be above the x axis, which makes B incorrect. B will be below the x axis. If you have a graphing calculator or know where there is one of the net, you can try it.

A and D are both wrong. The 1/2 does not become 2. What will happen is that 2 will make the graph wider.

There's only 1 answer left and that is
C <<<<<===== answer.
C reflects right across the y axis.
