     1)

     k^x

     2k^(x + 5) - 6

     sqrt(abs(2 k^(x + 5) - 6)^2 + abs(k^x)^2)

     2)

     log x

     log(-x + 3) + 2

     sqrt(abs(log(3 - x) + 2)^2 + abs(log(x))^2)

    You should learn to identify various transformations of a function:

    Reflections:

    vertical: -f(x), horizontal: f(-x)

    Translations (shifts):

    vertical: f(x) + k, horizontal: f(x + k)

    Dilations:

    vertical: k * f(x), horizontal f(kx)

    PROBLEM 1:

    Your original function is:

    f(x) = k^x

    Your transformed function is:

    g(x) = 2 * f(x + 5) - 6

    That's a horizontal dilation (compression) by a factor of 2 in width.

    Then a shift of 5 units to the left.

    And a shift of 6 units down.

    PROBLEM 2:

    Your original function is:

    f(x) = log(x)

    Your transformed function is:

    g(x) = log(-x + 3) + 2

    That's a horizontal reflection (across the y-axis).

    There's a shift of 3 units to the left.

    And a shift of 2 units up.
