Evertonl4b4 Vamos calcular as expressões dadas usando as funções \(f(x) = x + 1\) e \(g(x) = 2x + 3\):

a) \(f(g(x))\):
\(f(g(x)) = f(2x + 3) = 2x + 3 + 1 = 2x + 4\)

b) \(f(g(-2))\):
\(f(g(-2)) = f(2(-2) + 3) = f(-1) = -1 + 1 = 0\)

c) \(g(f(x))\):
\(g(f(x)) = g(x + 1) = 2(x + 1) + 3 = 2x + 2 + 3 = 2x + 5\)

d) \(g(f(2))\):
\(g(f(2)) = g(2 + 1) = g(3) = 2(3) + 3 = 6 + 3 = 9\)

e) \(-4f(g(x))\):
\(-4f(g(x)) = -4(2x + 4) = -8x - 16\)
