6. the expression b^2 - 4ac in the quadratic formula
7. a measure of how much a typical value in a set of data differs from the mean
10. when a function has a the variable 'x' as an exponent
11. a transformation that causes the graph to get wider (shrink toward the x-axis
12. an apparent solution that must be rejected because it does not satisfy the original equation

1. the set of all possible input values of a function
2. a transformation that causes the graph to narrow (stretch away from the x-axis)
4. a u-shaped graph of a quadratic function
5. when each input has exactly one output
