Question

Dado, f(x) = 5x - 2, calcule: a) f(1/2) b) f(-2) c) f(3/4).​

Answer 1

Resposta:

Explicação passo-a-passo:

a) f(1/2) = 5(1/2) - 2

f(1/2) = 5/2 - 2

f(1/2) = (5-4) / 2

f(1/2) = 1/2

b) f(-2) = 5(-2) - 2

f(-2) = -10 - 2

f(-2) = -12

c) f(3/4) = 5(3/4) - 2

f(3/4) = 15/4 - 2

f(3/4) = (15-8) / 4

f(3/4) = 7/4
