If 
and –3 ≤ λ ≤ 2, then write the range of 
Given that 
and -3≤λ≤2
We have to figure out range of 
In calculating the modulus of a vector multiplied by a scalar quantity, the sign of the scalar quantity does not matter, only it’s absolute value does.
Hence the minimum value of 
when λ=0 and maximum value of 
when λ=-3.
