Comparing Functions

2. The set of input values of a function.
4. A mathematical statement that two expressions are equivalent.
6. A function whose input is squared. This means there will always be two inputs that yield the same output.
8. A vertical line (x=a) that divides a parabola into two symmetrical halves.
11. An equation written as f(x) to represent the output.
12. The input that yields the minimum or maximum output value of a quadratic function. Turning point or axis of symmetry for a parabola.
14. The value of the output when the input is zero. The location where the graph of a function touches the y-axis.
15. A graph is defined as what is going on at the ends of each graph.
16. The horizontal axis in a coordinate plane.
18. The set of output values of a function.
19. The form , where are real numbers and n is a nonnegative integer. In other words, a ________ is the sum of one or more monomials with real coefficients and nonnegative integer exponents.
20. The vertical axis in a coordinate plane.

1. A symmetrical curve formed by a quadratic function.
3. A relation in which every input value is paired with exactly one output value.
5. Method used to solve a quadratic equation that cannot be factored.
7. A function whose value is a constant raised to the power of the argument, especially the function where the constant is e.
9. A function that is not a linear function.
10. The ___________ is represented by the slope of a line.
13. A group of symbols that make a mathematical statement
17. Those whose graph is a straight line.
