Question

se f(x)=3x+5 e g(x)=8x+1 calcule

a) F(g(x))

b)g(f(x))

c)f(f(x))

d)g(g(x))

Answer 1

Olá, tudo bem?

a) f(g(x)) = 3(8x + 1) + 5  →  f(g(x)) =  24x + 8

b) g(f(x)) = 8(3x + 5) + 1  →  g(f(x)) = 24x + 41

c) f(f(x)) = 3(3x + 5) + 5  →  f(f(x)) = 9x + 20

d) g(g(x)) = 8(8x + 1) + 1  →  g(g(x)) = 64x + 9

É isso!! :)
