f (x) = 5 - l -2 x -1 l , calcule
a) f ( -3) = 5 - l -2(-3) -1 l ==> 5 - l 6 -1 l ==> 5 - l 5 | ==> 5 - 5 ==> 0
========================================================
b) f (0) = 5 - l -2(0) -1 l ==> 5 - l 0 -1 l ==> 5 - l - 1 | ==> 5 - 1 ==> 4
========================================================
c) f ( 5) = 5 - l -2(5) -1 l ==> 5 - l -10 -1 l ==> 5 - l -11 | ==> 5 - 11 ==> - 6
========================================================
d) f ( 0) / f ( 7^2) = - 4
94
=========================================================
f (0) = 5 - l -2(0) -1 l ==> 5 - l 0 - 1 l ==> 5 - l - 1 | ==> 5 - 1 ==> 4
f (7^2)=f(49) = 5 - l -2(49) -1 l=>5 - l -98 -1 l=> 5 - l - 99 |=> 5 - 99 ==> - 94
