Question

se alguem soube responde.

Answer 1

Resposta:

5- f(x) = y = x + 1, valores de x = -2, -1, 0, 1, 2

→ f(-2) = y = -2 + 1 = -1 → (-2, -1)

→ f(-1) = y = -1 + 1 = 0 → (-1, 0)

→ f(0) = y = 0 + 1 = 1 → (0, 1)

→ f(1) = y = 1 + 1 = 2 → (1, 2)

→ f(2) = y = 2 + 1 = 3 → (2, 3)

6- Vm = ΔS/Δt

→ 90 = ΔS/1 → 90 . 1 = ΔS → ΔS = 90km/h

→ 90 = ΔS/2 → 90 . 2 = ΔS → ΔS = 180km/h

→ 90 = ΔS/3 → 90 . 3 = ΔS → ΔS = 270km/h

→ 90 = ΔS/4 → 90 . 4 = ΔS → ΔS = 360km/h

→ 90 = ΔS/5 → 90 . 5 = ΔS → ΔS = 450km/h

7- f(x) = 2x, valores de x = -2, 0, 1, 3

→ f(-2) = 2 . (-2) = 4

→ f(0) = 2 . 0 = 0

→ f(1) = 2 . 1 = 2

→ f(3) = 2 . 3 = 6
