AP Pre-Cal Function Vocab
Across
- 5. the x-coordinate of the point at which the graph crosses the x-axis *y value = 0
- 6. ____Lines- In a plane any two oblique lines, the product of whose slope is -1. They have opposite & reciprocal slopes.
- 8. An equation that has no operations other than addition, subtraction, and multiplication of a variable by a constant
- 9. If no vertical line intersects a graph in more than point, then the graph represents a function
- 14. ______Form -The equation of a line in the form y=mx+b, where m is the slope and b is the y-intercept
- 15. ____Line- a line that runs from north to south, has an undefined slope. Equation is y = #
- 16. _____Form -An equation in the form y-y1=mx-x1 where (x1,y1) are the coordinates of a point on the line and m is the slope of the line.
- 18. _____Lines- Non-vertical coplanar lines with the same slope
- 19. The set of all possible output values (commonly the “y” variable) which result from using a particular function.
- 21. A function whose ordered pairs satisfy a linear equation.
- 23. ____Relation- A relation that can be graphed with a line or smooth curve
- 25. A set of equations with the same variables
- 27. An equation of y in terms of x can be rewritten so that y=f(x)
- 28. a way to express the input and values that are represented on a graph, usually in the form (x, y)
- 29. The other variable in a function, usually y, whose value depends on x.
- 30. ____Relation- A relation in which the domain is a set of individual points
Down
- 1. ____Relation- A relation that has straight line graphs
- 2. A relation in which each element of the domain is paired with exactly one element in the range. *every x can only have one y*
- 3. a set of inequalities with the same variables.
- 4. the y-coordinate of the point at which the graph crosses the y-axis *x value = 0
- 7. ____Line -a line that runs from east to west, has a slope of 0. Equation is x = #
- 10. In a function, the variable, usually x, whose values make up the domain
- 11. The ratio of change in y-coordinates to the change in x-coordinates. Often expressed as rise/run formula: m=y2-y1x2-x1
- 12. A set of ordered pairs.
- 13. How much a quantity changes on average, relative to the change in another quantity, over time
- 17. a mathematical sentence that uses symbols such as <, >, <, or >, to compare two quantities.
- 20. ____Function- A function where each element of the range is paired exactly with one element of the domain
- 22. The set of all possible input values (commonly the “x” variable) for which a function is mathematically defined.
- 24. ____Relation- Relations that are not linear
- 26. _____Form -A linear equation written in the form Ax+By=C, where A,B, and C are integers whose greatest common factor is 1, A > 0, and A and B are not both zero
