 is where the picture exists from left to right; domain is a description of ALL the x-coordinates used on the picture. Think of the entire picture as casting a shadow on the x-axis, and describe all the x values that are covered. Using interval notation, describe by the x-coordinates, left to right. Domain is where the picture exists from bottom to top; range is a description of ALL the y-coordinates used on the picture. Think of the entire picture as casting a shadow on the y-axis, and describe all the y values that are covered. Using interval notation, describe by the y-coordinates, bottom to top. RANGE is the ONLY description we use the y-coordinates to describe because range is a description of all the y values you see. Range is where the picture is going UP from left to right. As you read from left to right (for bigger and bigger x’s), the y-values are also getting bigger. The slope connecting any two points on an increasing portion of the graph is positive. Using interval notation, describe by the x-coordinates, left to right Increasing is where the picture is going DOWN from left to right. As you read from left to right (for bigger and bigger x’s), the y-values are getting smaller. The slope connecting any two points on a decreasing portion of the graph is negative. Using interval notation, describe by the x-coordinates, left to right. Decreasing is where the picture is FLAT or HORIZONTAL from left to right. As you read from left to right (for bigger and bigger x’s), the y-values stay the same (are constant). The slope connecting any two points on a constant portion of the graph is 0. Using interval notation, describe by the x-coordinates, left to right. Constant is where the picture is strictly above the x-axis, where all the y-values are positive. Any x-intercept number is a boundary number and should NOT be included. Using interval notation, describe by the x-coordinates, left to right. Positive is where the picture is strictly below the x-axis, where all the y-values are negative. Any x-intercept number is a boundary number and should NOT be included. Using interval notation, describe by the x-coordinates, left to right. Negative is where the picture is bending up from left to right (looks “like a cup”). The slopes connecting consecutive points on a concave up portion of the graph will be getting bigger. Using interval notation, describe by the x-coordinates, left to right. Concave Up is where the picture is bending down from left to right (looks “like a frown”). The slopes connecting consecutive points on a concave down portion of the graph will be getting smaller. Using interval notation, describe by the x-coordinates, left to right. Concave Down: are where the graph crosses the x-axis. All XI have a y-coordinate of 0. x-intercepts are where the graph crosses the y-axis. All YI have a x-coordinate of 0. y-intercepts the absolute lowest point on the graph Minimum the absolute highest point on the graph. Maximum the y-coordinate for the point in question minimum / maximum VALUE: the xcoordinate of the point in question for what x does the function reach its minimum / maximum value
