Answer 1

                    VALOR NUMÉRICO

Primero hallamos los valores numéricos.

P(0) = 2(0)² + 0 - 4

P(0) = 2(0) + 0 - 4

P(0) = 0 + 0 - 4

P(0) = 0 - 4

P(0) = -4

----------------------------

P(2) = 2(2)² + 2 - 4

P(2) = 2(4) + 2 - 4

P(2) = 8 + 2 - 4

P(2) = 10 - 4

P(2) = 6

----------------------------

P(-1) = 2(-1)² + (-1) - 4

P(-1) = 2(1) - 1 - 4

P(-1) = 2 - 1 - 4

P(-1) = 1 - 4

P(-1) = -3

----------------------------

P(-2) = 2(-2)² + (-2) - 4

P(-2) = 2(4) - 2 - 4

P(-2) = 8 - 2 - 4

P(-2) = 6 - 4

P(-2) = 2

----------------------------

Hallamos E

$\mathrm{E=\frac{-4+6}{-3-2} }\\\\\LARGE\boxed{\mathbf{E=\frac{2}{-5} }}$

RPTA: -2/5
