Question

Y = f (x) = (x-1)/(x+2) ; calcular: f (3); f (1/2) ; f (-2)

Answer 1

Respuesta:

F(X) = (X-1)/(X+2)

F(3) = ((3)-1)/((3)+2)

F(3) = 2/5 =====> Respuesta

F(1/2) = ((1/2)-1)/((1/2)+2)

F(1/2) = (1/2)/(3/2)

F(1/2) = 1/3 =======> Respuesta

F(-2) = ((-2)-1)/((-2)+3)

F(-3) = -3/1

F(-3) = -3 ========> Respuesta
