  2. 2. Intercepts • The x-intercepts of a function are the x-coordinates of the points where the graph of the function intersects the x-axis. • The y-intercept of a function is the y-coordinate of the point where the graph of the function intersects the y-axis.
  3. 3. Given the graph of the function g find the value of: g(0) = g(1) = g(-2) = g(3) = Identify all intercepts.
  4. 4. The domain of a relation is the set of real numbers. The following are some of the ordered pairs associated with the relation. Write a rule (equation) Sketch the graph. for this relation. Is it a function?
  5. 5. Find the next three terms in each sequence of numbers ... 4, 7, 10, 13, , , 3, 6, 12, 24, , , 32, 16, 8, 4, , , 1, 1, 2, 3, 5, 8,13, , ,
