Question

si f(x) =1-2x-x²/x+1. hallarA= f(-2) + f(1) / 2​

Answer 1

Explicación paso a paso:

f(x) =1-2x-x²/x+1. hallarA= f(-2) + f(1) / 2

• f(-2) =1-2(-2)-(-2)²/-2+1

• f(-2) = 1 +4 -4/-2 + 1 = 5+3 = 8

• f(1) =1 -2(1)  -(1)²/1 +1

• f(1) =1-2 -1/1 +1 = -1

hallarA= f(-2) + f(1) / 2 = 8 -1/2 = 17/2 = 8.5

espero que sirva se ayuda
