Question

Si: P(x) = 3x + 5
Calcular: M = P(a + 2) – P(a - 2)
Rpta.: …………………..

Answer 1

Respuesta:

10 :3

Explicación paso a paso:

P(x) = 3x + 5

P(a + 2) = 3(a + 2) + 5

P(a + 2) = 3a + 6 + 5

P(a + 2) = 3a + 11

P(a - 2) = 3(a - 2) + 5

P(a + 2) = 3a - 6 + 5

P(a + 2) = 3a - 1

M = P(a + 2) – P(a - 2)

M = (3a + 11) - (3a - 1)

M = 3a + 11 - 3a + 1

M = 10
