 "Evaluation A. How often are these statements true? Write always, sometimes or never on the space before each item 1. Changing the sign of a quadratic inequality also changes its solution set. 2. The solution set of a quadratic inequality is best written as an absolute value inequality 3. There is a solution set for every quadratic inequality. 4. The critical values of a quadratic inequality may also be used as test points. 5. The critical values of a quadratic inequality are equal to the roots of the corresponding equation 6. The critical values of a strict quadratic inequality are part of its solution set. _7. If the test point of an interval yields a positive value, then that interval is part of the solution set of the given quadratic inequality 8. There is a quadratic inequality whose entire solution set is the interval [4,00). 9. If a quadratic equation has roots which are not purely real numbers then the solution set of any inequality derived from that equation is the empty set. 10. The critical values of a quadratic inequality may also be used as points." Asked by: Guest | Views: 85
