Now when does an absolute value function like this, when is this going to hit a minimum point? Well, the absolute value of something is always going to be non-negative. So it hits a minimum point when this thing is equal to 0. Well, when is this thing equal to 0? When x equals 1, this thing is equal to 0. So we hit a minimum point when x is equal to 1. And when x equals 1, this term is 0, absolute value of 0 is 0. g of 1 is 1.
