Graphs of Constant, Linear, and Quadratic Functions

Answers to Activities Questions

1.  There are no real zeros. This is a constant function. Its graph is a horizontal line through
      (0 , - 2)

                

2.  There are no real zeros. This is a constant function. Its graph is a horizontal line through
      (0 , )

3.  One zero at x = 0. This is a first degree or linear function. One other point (2 , 4).

4. One zero at x = 2.  This is a first degree or linear function. One other point (4 , - 1).

5.  One zero at x = 4.  This is a first degree or linear function. One other point (2 , - 6).

                           

6.  One zero at x = -3 and another at x = 5. This is a quadratic function. One other point (mid 
     way between zeros) is (1 , - 16)

7.  One zero at x = -1 and this is a double root. This is a quadratic function. One other point to 
     determine location is (1 , - 4)

8.  One zero at x = 3 and another at x = 7. This is a quadratic function. One other point (mid 
     way between zeros) is (5 , - 4)

9.  One zero at x = - 1 and another at x = . This is a quadratic function. One other point (mid 
     way between zeros) is ( , - )

10.  One zero at x = 4 and this is a double root. This is a quadratic function. One other point is
        ( 6 , 2)
