... For 2 sets, the domain and the range, a function associates for every element of the domain exactly one element of the range. Examples: Given a box of apples, if for every apple we obtain its weight we have a function. This maps the set of apples into the real numbers. Domain=range=all real numb ...

... This solution is always true because r can be replaced with any number and each side of the equation will always be true. Equations that are always true will show the same thing on each side throughout solving each step. In the second line of the equation 3r - 2 = 3r -2 is shown. At this step in sol ...
