Given the following functions f (x) and g (x), solve f[g (6) ].

f (x) = 6x + 12

g (x) = x - 8

f[g (6) ] = 0

Step-by-step explanation:

f (x) = 6x + 12

g (x) = x - 8

f[g (6) ]

First lets find g (6)

g (6) = 6-8 = - 2

Then we substitute - 2 in for g (6)

Putting - 2 into f (x)

f[g (6) ] = f (-2) = 6 (-2) + 12 = - 12+12 = 0
