x intercepts, y intercepts, zeroes, vertex or turning point, intervals , range ,domain

X intercept  y intercept
X intercepts: The points where the graph crosses the x axis. The y coordinate will be zero.   Y intercepts: The points where the graph crosses the y axis. The x coordinate will be zero

zero vertex
 Zeroes: Points on the graph that have y coordinate values of zero. Look at x-intercepts. The words are different but zeros and x intercepts are asking for the same points.  Vertex: The point or points on a graph where the line changes from decreasing (heading down) to increasing (heading up) or vice-versa. Another word for vertex is a turning point.

decreasing interval increasing interval
Decreasing intervals are the parts of the graph that go down from left to right. To write up the interval, Use left and right values.Here, (-∞, 1) NOTICE IT"S THE X COORDINATE FROM THE VERTEX.  Increasing intervals are the parts of the graph that go up from left to right. To write up the interval, Use left and right values.Here, (1,∞) NOTICE IT"S THE X COORDINATE FROM THE VERTEX.

domain range
Domain is the set of values on the x axis that the function will use. The first value is how far left it goes, and the second value is how for right it goes. Here, (- ∞, ∞).  Range is the set of values on the y axis that the function will use. The first value is how far down it goes, and the second value is how far up it goes. Here,[-2, ∞). NOTICE THE VERTEX VALUE USED IS THE Y COORDINATE.

End Behavior: The left side always starts with "as x→-∞", then look at your graph. If the end heads down, add "y→-∞  ". If the end heads up, add "y→∞".  The right side always starts with "as x→∞", then look at your graph. If the end heads down, add "y→-∞  ".If the end heads up, add "y→∞".
