Answer:
when rounding anything that is or is greater than 5 you round up 1.
4,->7<-08.06
so rounding up 1, 4 would turn into 5.
 
        
                    
             
        
        
        
Answer:
1,-3,-5
Step-by-step explanation:
Given:
 f(x)=x^3+7x^2+7x-15
Finding all the possible rational zeros of f(x)
p= ±1,±3,±5,±15 (factors of coefficient of last term)
q=±1(factors of coefficient of leading term)
p/q=±1,±3,±5,±15
Now finding the rational zeros using rational root theorem
f(p/q)
f(1)=1+7+7-15
    =0
f(-1)= -1 +7-7-15
      = -16
f(3)=27+7(9)+21-15
     =96
f(-3)= (-3)^3+7(-3)^2+7(-3)-15
      = 0
f(5)=5^3+7(5)^2+7(5)-15
     =320
f(-5)=(-5)^3+7(-5)^2+7(-5)-15
       =0    
f(15)=(15)^3+7(15)^2+7(15)-15
      =5040 
f(-15)=(-15)^3+7(-15)^2+7(-15)-15
       =-1920
Hence the rational roots are 1,-3,-5 !

There are an infinite number of them.
Here are a few:
2.1
2.2
2.3
2.3000000001
2.30000000000000006
2.5
2.00009
.
.
etc.
How to find them:
You probably never heard this before, but I'll bet 
you'll remember it from now on:
<em>ANY number that you can write down on paper completely, </em><em>using digits 
and a decimal point if you need it but no symbols, is a rational number.</em>
If you can write it down completely without any 'comments', then it's rational.
