Question

Dada a função g(x) = 2x² + 4x, determine:
a) g(0)+g(-1):
b) g(2)+g(3)-g(1):​

Answer 1

Resposta:

Explicação passo a passo:

a.

g(0)=2.0²+4.0=2.0+4.0=0

g(-1)=2.(-1)²+4.(-1)=2.1-4=2-4=-2

g(0)+g(-1)=0-2=-2

b.

g(2)=2.2²+4.2=2.4+8=8+8=16

g(3)=2.3²+4.3=2.9+12=18+12=30

g(1)=2.1²+4.1=2.1+4=2+4=6

g(2)+g(3)-g(1)=

16+30-6=

46-6=

40
