... Theorem: If A is any set then A. Proof: (by contradiction) Suppose not. Then there is a set with no elements and a set A such that is not a subset of A. Therefore the statement “x is an element of implies that x is an element of A” is false. This means that there is an x such that xA. But ...

... State the Leading Coefficient Test. As x moves without bound to the left or to the right, the graph of the polynomial function f(x) = anxn + . . . + a1x + a0 eventually rises or falls in the following manner: 1. When n is odd: a. If the leading coefficient is positive, the graph falls to the left an ...

... (F) Properties of Complex Numbers From the example on the previous slide, we see that the resultant number (-1 + i) has two parts: a real number (-1) and an imaginary number. This two parted expression or number is referred to as a complex number. The number 4 can also be considered a complex numbe ...
