Across
- 5. Diagram: a diagram that shows how a specific relation maps input values to output values
- 6. Line Test: a method for testing whether a given graph is that of a function; if a vertical line can be drawn that intersects the graph in more than one point, then the graph does not represent a function; if no such line can be drawn, the graph is a function
- 7. a number that is entered into a function or relation; the input variable in a function is the independent variable
- 8. the result of a function or relationship; the output variable in a function is the dependent variable
Down
- 1. Pair: a pair of numbers in parentheses that names the location of a point on a coordinate plane; the first number is the x-value, and the second number is the y-value
- 2. the ordered pair (-2, 3) is located 2 units to the left of and 3 units up from the origin (0,0)
- 3. a relationship that pairs input values with output values; a relation is also a function if each input value maps to exactly one output value.
- 4. a rule that tells how one number depends on another; for each input number, there is exactly one output number
