l,m,n are d.c's so range of l is between 0 and 1(range of cosx)
same is the range of m and n.
0 <= l <=1
multiply by -3,
0<= -3l <= -3_______________(1)
similarly for m,
0<= 4m <=4---------(2)
for n
0<= n <= 1-----(3)
(1)+(2)+(3),

0<= -3l+4m+n <= 2
so range is [0,2]

correct me if m wrong
!!!!!!!!!!!!!!!!!!!!!
