Question

Se da functia f:R cu valori in R , unde f(x)= -x +8 . Sa se calculeze f(-2014)×f(-2013)×....×f(2013)×f(2014)

Answer 1

f(x) = 0 
-x + 8 =0 
x = 8 
f( -2014) ······· f( 8) ····· f( 2014) = 0 
pentru ca          ↓
                      = 0

Answer 2

Calculezi f(x)=0. f(x)=-x+8=0
-x+8=0
-x=0-8
-x=-8|•(-1)
x=8
=> f(-2014)xf(-2013)xf(8)x...xf(2013)xf(2014)=0
