polynomial functions

Show step by step work for solution of the each problem

Quiz 4

 

 

In #1 and #2 select one of the following four sketches
to describe the ends behavior of the graph
of the given polynomial function
 

1.      F(x) = x4 – 4x2 + x + 5


2.      F(x) = ‒ x3 + x2 ‒ 1

3.  Find the zeros of the polynomial function and construct a sign diagram for:    

f(x) = x3 + 5x2 – x – 5

4.  Use the zeros, sign diagram, y-intercept and the leading-term test end behavior to make a rough sketch of the function. Show the work and then the sketch.    

f(x) = x3 – x2 – 6x

5. Determine the vertical asymptotes of the graph of the function:
    f(x) =   

6. Determine the horizontal asymptote of the graph of the function:
    f(x) =   

 

Functions:

 

A) f(x) =  

B) f(x) =

 

C) f(x) =  


D) f(x) =



7. Mach one of the given rational functions with the following graph:

8. Find composition of function (f ° g)(x) and (g ° f)(x) for
   f(x) =        and       g(x) = x2 ‒ 5      

 

 

9. Solve quadratic inequality:  2x2 – 3x > 5

 


10. Solve rational inequality:   < 0

    Show steps.

 

11. Solve rational inequality and write solutions in interval form:     < 2
     Show steps.

 

 

12. Find inverse function f-1(x) for y = f(x) =   and calculate f-1(4).
