Resposta:
a) 7
b) -2
c) 21,8
d) 25
e) 5
f) 8,5
Explicação passo a passo:
F(1) = 3(1)+4
f(1) = 7
f(-2) = 3(-2) + 4
f(-2) = -2
f(-8,6) = 3(-8,6) + 4
f(-8,6) = 21,8
f(3/4) = 3(3/4) + 4
f(3/4) = 9/4 + 4
f(3/4) = 9/4 + 16/4
f(3/4) = 25
f(-1/2) = 3(-1/2) + 4
f(-1/2) = -3/2 + 4
f(-1/2) = -3/2 + 8/2
f(-1/2) = 5
f(1,5) = 3(1,5) + 4
f(1,5) = 8,5
