Q1:

Point +4 on the complex plane is

A 4 units above the origin on the j axis

B 4 units below the origin on the j axis

C 4 units right of the origin on the real axis

D 4 units left of the origin on the real axis

ANS:C - 4 units right of the origin on the real axis

Because there is x+jy form are consider so here we can write +4+0j that means x=4 and y=0 so the answer is C option.
