So we can solve that thing we inputted into our calculator. When does that equal zero? And actually, let's just do that right from the get-go. So in our calculator, we already inputted right over, let's make sure it's on. In our calculator, we already inputted the absolute value of f of x minus g of x. And so we can use our solver now to figure out when does that equal zero. And it actually equals zero just in the, where we see it, it equals it one time, two times, and three times.
