TRANSCRIPT

  • Slide 1
  • COORDINATE PLANE x-axisy-axis
  • Slide 2
  • COORDINATE PLANE QUADRANTS III III IV (+, +)(-, +) (-, -)(+, -)
  • Slide 3
  • GRAPHING Coordinates of point A is (-2, 4) A
  • Slide 4
  • Points in the coordinate plane are named by ordered pairs of the form (x, y) The first number, or x-coordinate, corresponds to the numbers on the x-axis. THE COORDINATE PLANE The second number, or y-coordinate, corresponds to the numbers on the y-axis.
  • Slide 5
  • COORDINATE PLANE NAME THESE POINTS (2, 4) A
  • Slide 6
  • COORDINATE PLANE NAME THESE POINTS (-1, -2) B
  • Slide 7
  • COORDINATE PLANE NAME THESE POINTS (-4, 0) C
  • Slide 8
  • COORDINATE PLANE NAME THESE POINTS (0, 3) D
  • Slide 9
  • A RELATION is a set of ordered pairs A relation can be represented by: A set of ordered pairs RELATIONS A table A graph An equation A mapping
  • Slide 10
  • A RELATION is a set of ordered pairs A relation can be represented by: A set of ordered pairs RELATIONS A table A graph An equation A mapping {(2, 3), (-5, 2), (3, 3)}
  • Slide 11
  • A RELATION is a set of ordered pairs A relation can be represented by: A set of ordered pairs RELATIONS A table A graph An equation A mapping x321 y5-40
  • Slide 12
  • A RELATION is a set of ordered pairs A relation can be represented by: A set of ordered pairs RELATIONS A table A graph An equation A mapping
  • Slide 13
  • A RELATION is a set of ordered pairs A relation can be represented by: A set of ordered pairs RELATIONS A table A graph An equation A mapping y = 2x - 3
  • Slide 14
  • A RELATION is a set of ordered pairs A relation can be represented by: A set of ordered pairs RELATIONS A table A graph An equation A mapping x y 3 5 2 7
  • Slide 15
  • Recall from Chapter 1, that in a relation The DOMAIN is the set of all first numbers of the ordered pairs. The RANGE is the set of all second numbers of the ordered pairs. RELATIONS
  • Slide 16
  • For the relation {(2, 5), (4, -2), (4, 0)} The DOMAIN is {2, 4} The RANGE is {-2, 0, 5} RELATIONS Do not repeat elements in a set. Write sets in numerical order
  • Slide 17
  • RELATIONS An INVERSE RELATION is obtained by switching the coordinates of each ordered pair. The inverse of {(5, 3), (6, -2), (5, 5)} is {(3, 5), (-2, 6), (5, 5)}
  • Slide 18
  • RELATIONS Change the following to a mapping: {(5, 3), (6, -2), (5, 5)} x y 5 6 -2 3 5
