The law of supply<span> states that the quantity of a good </span>supplied<span> (i.e., the amount owners or producers offer for sale) rises as the market price rises, and falls as the price falls. Conversely, the </span>law<span> of </span>demand<span> (see </span>demand<span>) says that the quantity of a good demanded falls as the price rises, and vice versa.</span>
Think of it as -5+1i/2i, since 1i=i. From there, the i's could cancel out since dividing a number by itself would just equal 1. It would then be -5+1/2 which would be simplified to -4 1/2. No need to worry about those i's at all!
It’s not a function because the domain (the X) is repeating...
X cannot repeat if you want it to be a function
