Thus the domain of h(x), which is the domain of (g(x))¡1, is the set of all real numbers x such that g(x) 6= 0, which is precisely what the quotient rule tells us.

Looking at successively higher powers of j, we cycle through the four values, +j, –1, –j, +1. A number, like jb, that has a negative value for its square, is known as

This is an axiomatic definition: properties I-V are taken to be axioms - statements considered to be true. All other properties of real numbers are deduced from these five, using logic.

This equality can be veri ed by considering cases. One of the four possible cases is checked as follows: Suppose x < 0 and y 0. Then xy is 0 and we have jxyj= (xy) = ( x)y = jxjjyj.
