Graphs of Constant, Linear, and Quadratic FunctionsAnswers to Self Test1. There are no real zeros. This is a constant function. Its graph is a horizontal line through (0 , 5).
2. One zero at x = - 3. This is a first degree or linear function. One other point (0 , 6).
3. One
zero at x = -
4. One zero at x = - 4 and another at x = 1. This is a
quadratic function. One other point (mid
way between zeros) is (-
5. One zero at x = 3 and this is a double root. This is a
quadratic function. One other point
is (0 , -
6. One zero at x = - 2 and another at x = 2. This is a quadratic function. One other point (mid way between zeros) is (0 , - 12).
7. One zero at x = - 5 and another at x = - 1. This is a quadratic function. One other point (mid way between zeros) is (- 3 , - 4).
8. One zero at x = -
