1 - Dadas as funções de Rem R, f(x) = x + 5
e g(x) = x2 +5x, calcule:
a) f(0) + g(0)
b) f(-5) - g(1)
c) f(2) - g(5)
d) [f(3) + g(2)]. f(-3)

Answer 1

Resposta:

A) F(0) + G(0)

F(0)=0+5=5     G(0)=0*2+5*0=0        0+5=5

B) F(-5) - G(1)      

F(-5)= -5+5=0   G(1)= 1*2+5*1= 7          0-7=-7

C) F(20) - G(5)

F(20)= 20+5=25     G(5)=5*2+5*5=35    35-25=10

D) [f(3)+ g(2)] . F(-3)

F(3)= 3+5= 8 + G(2)= 2*2+5*2=14         14+8=22

F(-3)= -3+5=2         2*22=44
