    inverse functions

    I got some questions for functions. Need some help

    1)Solve for K if f(x)=2k(3x+2), and f^-1(4)=6

    2) Describe the sequence of functions that will transform f(x)=x^2 into g(x)=2x^2-12x+7
    I just need the step by step transformation

    I just need the step by step transformation
    1) f^{-1}(4)=6 \Rightarrow f(6) = 4 \, ....

    2) g(x) = 2x^2-12x+7 = 2(x - 3)^2 - 11. What does this tell you ....?
