Question

AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA

Answer 1

Explicação passo-a-passo:

• f[g(x)] = f(3x + m)

f[g(x)] = 2.(3x + m) + 3

f[g(x)] = 6x + 2m + 3

• g[f(x)] = g(2x + 3)

g[f(x)] = 3.(2x + 3) + m

g[f(x)] = 6x + 9 + m

Como f[g(x)] = g[f(x)]:

6x + 2m + 3 = 6x + 9 + m

6x - 6x + 2m - m = 9 - 3

m = 6

• f(m) = f(6)

f(m) = 2.6 + 3

f(m) = 12 + 3

f(m) = 15

Logo:

14 + f(m) = 14 + 15

14 + f(m) = 29 -> número primo
