way to the
market. which equation
represents
liz's walk?
a 0+6/10=8/10
b 6/10+2/0=8/10
c 8/10-6/10=240
d 10-8/10=2/10

w'x is 0.

sample answer: you can determine whether each element of the domain is paired with exactly one element of the range. for example, if given a graph, you could use the vertical line test; if a vertical line intersects the graph more than once, then the relation that the graph represents is not a function.
