  1. log3(3x) = log3(3) + log3(x) = 1 + log3(x)
    f(x) is identical to g(x)

    g(x) is f(x)
    dilated in x by 3
    shifted up 1
    The two transformations cancel each other out

    the graphs of all exponential functions look the same
    dilating and shifting are complementary operations.
