Given a relation represented by the following ordered pairs, write an
equation expressing the relation.

   x     1       ...
x   1    2    3    4
y   5   10   15   20
A function is a relation, a set of ordered pairs (x, y), such that for each
value of x there is exactly one value of y.

  1. 1. Domain and Range: Matching Sets Matched set by flickr user K2D2vaca
  2. 2. Given a relation represented by the following ordered pairs, write an equation expressing the relation. x 1 2 3 4 y 5 10 15 20 Sketch the graph. What is the domain and range of the relation?
  3. 3. x 1 2 3 4 y 5 10 15 20
  4. 4. A function is a relation, a set of ordered pairs (x, y), such that for each value of x there is exactly one value of y. Is the relation A = {(2, 5), (7, 3), (6, 4), (5, –3)} a function? Is the relation given by the rule y² = x a function? Is the relation B = {(2, 7), (5, 11), (2, 5), (3, –1)} a function? Is the relation given by the rule y = 2x a function?
