    When you see f[g(x)], you're basically taking the result of g(x) and using that as the value of X in f(x). g(-6) = (1/2)(-6)-2 = ?

    So, this is what you do. First you substitute -6 for the x 's in the second equation then you substitute what you get there for the x 's in the first equation.

    g(-6) = (1/2)(-6)-2 = -5 f(g(-6)) = -5 - 4 = -9

    I got -5 for the second equation. Then entered that in the first and got -9 for the first equation.
