• Maximum: 1) the highest point on a graph, or 2) the biggest possible output of a function. Not all functions have a maximum

• Minimum: 1) the lowest point on a graph, or 2) the smallest possible output of a function. Not all functions have a minimum

• Increasing: a graph or part of a graph that goes up from left to right

• Decreasing: a graph or part of a graph that goes down from left to right

• x-intercept: the point(s) where the graph crosses the x-axis (where y is 0). A function can have any number of x-intercepts

• y-intercept: the point where the graph crosses the y-axis (where x is 0). A function has at most one y-intercept

• Domain: all the possible inputs (x-values) for a function

• Range: all the possible outputs (y-values) for a function
