Question

Se f (×) = 1 ,
× elevado a 2 + 1
Quanto vale f (-2) - f (2)

Answer 1

 x² + 1 = 1
f(-2) = ( - 2 )² + 1
f(-2) = 5

f(2) = 2² +1
f(2) = 5

f(-2) - f(2)
5 - 5 = 0

x² + 1 = 1
x² = 1-1
x² = 0

Answer 2

Boa noite Juliana

f(x) = x² + 1

f(-2) = (-2)² + 1 = 4 + 1 = 5
f(2) = (2)² + 1 = 4 + 1 = 5

f(-2) - f(2) = 5 - 5 = 0
