Question

1. Considere as funçoes f e g onde f(x) + 2x+4 e g(x)=x² determine
a)f(2)=
b)g(4)=
c) f(2).g(4)=
d)$\frac{g(4)}{f(2)}$ =

Answer 1

Olá,


a) f(2)= 2 × 2 + 4= 8
b) g(4)= 4² = 4 × 4= 16
c) f(2) × g(4)= (2 × 2 + 4) × (4²)= 8 × 16= 128
d) $\frac{g(4)}{f(2)}$= $\frac{(4²)}{2.2+4}$= $\frac{16}{8}$= 2
