Chapter 3 Self Test 1  

Press  for True  and    for False.

  

1.    

The correct graph of  y = 2(x-3)2 -1  is Graph  b.  
       

2)

This is the graph of   y = -(x + 1)2 + 3  written in standard form.

       

3. The x and y-intercepts: y = x2 - 5x + 4 are  (0, -4), (0, 1), (-4, 0).

        

4)  The maximum point on the graph of f(x) = -x2- 2x + 2  is ( -1,3).   ( Use a grapher )

       

5)  Use a graphing utility to estimate the range of  f(x) = x2+ 10x + 21.

 The range is [4, inf).    
          

6)All  the real zeros of the polynomial function:

f(x) = x3 - 3x2- 4x are x = -4, and 1

        

7)

 The correct graph of f(x)= x3 - 1/2 is Graph a.

        

8)   Divide: (x3 + 8) ÷ (x + 2).

The quotient  is x2 - 2x + 4.  
       

9)   Find all of the real solutions:   x3 - 7x + 6 = 0.

 x =  -2, -1, 3            
         

10) All possible rational zeros of  f(x) = 10x3 + 31x2 - 34x + 8 are
