Question

03) Construa o gráfico das seguintes funções Afim:

f(x) = x - 12

f(x) = 2x + 6

f(x) = - 2x - 3

Answer 1

Resposta:

y = 2*(–2) – 1 → y = –4 –1 → y = –5

y = 2*(–1) –1 → y = –2 – 1 → y = –3

y = 2 * 0 – 1 → y = –1

y = 2 * 1 – 1 → y = 2 – 1 → y = 1

y = 2 * 2 – 1 → y = 4 – 1 → y = 3

Explicação passo-a-passo:

y = 4 * (0,5)4 – 5 * (0,5)3 – 0,52 + 0,5 – 1 = 0,25 – 0,625 – 0,25 + 0,5 – 1 = – 1,155

y = 4 * 04 – 5 * 03 – 02 + 0 – 1 = –1

y = 4 * 14 – 5 * 13 – 12 + 1 – 1 = –2

y = (–1)³ = –1

y = 0³ = 0

y = 1³ = 1

y = 1,5³ = 3,375

y = 2³ = 8

y = (–2)² = 4

y = (–1)² = 1

y = (0)² = 0

y = (1)² = 1

y = (2)² = 4

 

y = 2*(–2) – 1 → y = –4 –1 → y = –5

y = 2*(–1) –1 → y = –2 – 1 → y = –3

y = 2 * 0 – 1 → y = –1

y = 2 * 1 – 1 → y = 2 – 1 → y = 1

y = 2 * 2 – 1 → y = 4 – 1 → y = 3
