The Zero Exponent
For any nonzero number a,
a⁰=?
a⁰=1
A function is...
A function is a correspondence between a first set, called the domain, and a second set, called the range, such that each member of the domain corresponds to exactly one member of the range.
The Verticle Line Test says...
If it is possible for a verticle line to cross a graph more than one, then the graph is not the graph of a function.
m = rise/run
= verticle change/horizontal change
= the difference in y/the difference in x
= y2-y1/x2-x1 = y1-y2/x1-x2
All are examples of Slope
