g(x) = 3x - 8
g(-4) = (3)(-4) - 8 = -12 - 8 = -20

g[g(-4)] = g(-20)

g(-20) = (3)(-20) - 8 = -60 - 8 = -68

Do it from the inside out.
g(-4) = 3(-4)-8 = -20
g(-20) = 3(-20) -8 = -68.

g(-4) = 3 * (-4) - 8 = -12 - 8 = -20
g(g(-4))=g(-20)= 3 * (-20) - 8 = -68

g(-4)=3(-4)-8
=-12-8=-20
3(-20)-8=
-60-8=-68
