I'm not a math guru but there are only 4 shapes in this and there are 5 functions? You can describe a circle with a single function. Someone explain?

f and g form the top an bottom of the circle. note that they only differ by a single sign

you need two of them because a circle can't be expressed by a single function of x as it needs to map every x value to 0 to 2 y values
