Question

Dada a função f(x)=3x+1, determine :

Answer 1

Resposta:

A) f(0) = 1

B) f(-1) = -2

C) f(-1) = -2

D) f(-2) = -5

E) f(-4) = -11

Explicação passo a passo:

A) f(0) = 3 * 0 + 1

f(0) = 1

B) f(-1) = 3 * (- 1) + 1

f(-1) = -3 + 1

f(-1) = -2

C) f(-1) = 3 * (- 1) + 1

f(-1) = -3 + 1

f(-1) = -2

D) f(-2) = 3 * (-2) + 1

f(-2) = -6 + 1

f(-2) = -5

E) f(-4) = 3 * (-4) + 1

f(-4) = - 12 + 1

f(-4) = -11
