Henry Barber · Answer 1

(g o f) (x) = g (f (x))

so

(g o f) (0) = g (f (0))

find f (0) and subsitute for x in g (x)

I'm assuming you mean f (x) = - 5x+1

f (0) = - 5 (0) + 1=1

g (f (0)) = g (1) = 1^3=1

(g o f) (0) = 1

because you have to subtract then carry the one then add it gain then get 20 plus one more
