Answer:
The given statement that value 5 is an upper bound for the zeros of the function f(x) = x⁴ + x³ - 11x² - 9x + 18  will be true.
Step-by-step explanation:
Given

We know the rational zeros theorem such as:
if  is a zero of the function
 is a zero of the function  ,
, 
then  .
.
As the  is a polynomial of degree
 is a polynomial of degree  , hence it can not have more than
, hence it can not have more than  real zeros.
 real zeros.
Let us put certain values in the function,
 ,
,  ,
,  ,
,  ,
,
  ,
,  ,
,  ,
,  ,
, 
From the above calculation results, we determined that  zeros as
 zeros as 
 and
 and  .
.
Hence, we can check that

Observe that, 
 ,
,  increases rapidly, so there will be no zeros for
 increases rapidly, so there will be no zeros for  .
.
Therefore, the given statement that value 5 is an upper bound for the zeros of the function f(x) = x⁴ + x³ - 11x² - 9x + 18  will be true.
 
        
             
        
        
        
Answer:
the first option
Step-by-step explanation:
really, just look at the table.
is the mean value (10.4) larger than the median (13.4) ?
I hope you can see right away that it is not. 
and you can see they are not the same either.
so, all the answer options mentioning mean larger than median or equal to median can be ruled out right away.
so, it is between the first two options.
now think ! how do we draw number lines ? a coordinate axis ?
the smaller numbers left, the larger numbers right. the numbers grow from left to right. 
the mean value is simply the sum of all measurements divided by the number of measurements (how many median were done). if that is smaller that the median (so, the Mean is left of the Median), it means that the majority of measurements had a result smaller (to the left) than the Median. so, it is skewed-left.
 
        
             
        
        
        
For this case we must find the value of the variable of the following equation:

Subtracting  from both sides:
 from both sides:

Subtracting 4 from both sides:

Multiplying by 6 on both sides:
