Question

se considera functia f:R-R,f(x)=x-3.Calculati produsul P=f(-3)xf(-2)x...x f(3)

Answer 1

observam ca         f(3) = 3 - 3 =0 
atunci f( -3) ············ f(3) = 0 
                                 ↓
       un termen este   0 

Answer 2

$f(-3)=-6 \\ f(-2)=-5 \\ f(-1)=-4 \\ f(0)=-3 \\ f(1)=-2 \\ f(2)=-1 \\ f(3)=0$
Produsul este $(-6)*(-5)*(-4)*(-3)*(-2)*(-1)*0=0$
