Answer:
The correct option is C.
Step-by-step explanation:
The given cubic equation is

According to the rational root theorem 1 and -1 are possible rational roots of all polynomial.
At x=-1, the value of function 0. Therefore (x+1) is the factor of polynomial and -1 is a real root.
Use synthetic division to find the remaining polynomial.
 
 
Using 
 
USe zero product property and equate each factor equal to 0.

Therefore the equation have three real roots out of which the value of two roots are same.
Option C is correct.
 
        
                    
             
        
        
        
The last image is the graph of 
In fact, it is an increasing exponential function, and it passes through the points  , which reflects the fact that
, which reflects the fact that  and
 and  , which reflects the fact that
, which reflects the fact that  .
.
Now,  is a child of the parent function we just described. Precisely, it is the result of the transformation
 is a child of the parent function we just described. Precisely, it is the result of the transformation 
In general, every time you perform a transformation like  , you translate the graph horizontall, k units to the left if k is positive, and k units to the right if k in negative.
, you translate the graph horizontall, k units to the left if k is positive, and k units to the right if k in negative.
Since in this case  , we have a horizontal translation of 4 units to the right.
, we have a horizontal translation of 4 units to the right.
So, the correct option is the third one, because:
- The first graph is the parent function translated 4 units to the left
- The second graph is the parent function translated 4 units down
- The third graph is the parent function translated 4 units to the right
- The fourth graph is the parent function

Answer:
X =3 and x =6
Step-by-step explanation:
Just look at the line where they cross another line,
 
        
                    
             
        
        
        
Answer:
16
Step-by-step explanation:
So for QR is 1-(-3)=4
QT:|-2-2|=4
TS: |-2-(-2)|=4
RS: 2-(-2)=4
and they plus together is 4x
4x4 = 16 
I hope this helps, have a blessed day. :D
