BELLRINGER:The graph below represents Maria’s distance from home one day as she rode her bike to meet friends and do a couple of errands for her mom before returning home. • What do the horizontal lines on the graph represent? • Where in the graph shows her taking care of the 2 errands? • Compare how she traveled at the beginning to how she traveled at the very end. • Create Maria’s story so that it matches the graph.

Intercepts • x-intercept – the point at which the line intersects the x-axis at (x, 0) • y-intercept – the point at which the line intersects the y-axis at (0, y)
Find the x and y intercepts, then graph. -3x + 2y = 12
Increasing, Decreasing, or Constant • Sweep from left to right and notice what happens to the y-values • Increasing goes up (L to R) • Decreasing falls down (L to R) • Constant is a horizontal graph
Continuous vs Discrete • Continuous has NO breaks • Discrete has gaps or breaks
Extrema • Minimum Point – least value of the function • Maximum Point – greatest value of the function
Domain & Range • Domain – all x-values of a function • Range – all y-values of a function
Notation • Interval – represents an interval as a pair of numbers. The numbers are the endpoints of the interval. Parentheses and/or brackets are used to show whether the endpoints are excluded or included • Set– using inequalities to describe the values
Asymptote A line that a graph gets closer and closer to, but never crosses or touches
