Across
- 2. the point at which the graph crosses the x-axis (also called the zeros)
- 5. when two or more fractions have the same denominator
- 8. a line that a curve approaches, as it heads towards infinity.
- 10. a root of a transformed equation that is not a root of the original equation because it was excluded from the domain of the original equation.
- 11. allow us to create functions defined over numbers that work for our purposes
- 12. the set of all input values (x-values) that satisfy the given function without restriction
- 14. where the value of the function f(x) decreases with an increase in the value of x
- 15. the point at which the graph crosses the y-axis
Down
- 1. where the value of the function f(x) increases with an increase in the value of x
- 3. an equation in which two ratios are set equal to each other
- 4. a rational expression that has a fraction in its numerator, denominator or both
- 6. a function that can be written as a polynomial divided by a polynomial
- 7. the point at which a mathematical function is no longer continuous.
- 9. behavior the behavior of the graph as x approaches positive or negative infinity
- 13. the set of all outputs of a relation or function; the set of y-values for which a function is defined
