Question

Considerando f : R → R, com f(x) = x(elevado a 4) + 6x² − 32. Encontre f(−1), f(2) e f(5).

Answer 1

Resposta:

Explicação passo a passo:

f(-1)=

(-1)^4+6(-1)^2-32=

+1+6.1-32=

1+6-32=

-25

f(2)=

2^4+6.2^2-32=

16+6.4-32=

16+24-32=

40-32=

8

f(5)=

5^4+6.5^2-32=

625+6.25-32=

625+150-32=

775-32=

743
