Answer:
The correct answer is 64 times Geri’s original answer
Step-by-step explanation:
Given
Gari's Answer: 2³
Correct Answer: 2⁹
Required:
Relationship between both answers
Let Gari's answer be represented by G and the Correct answer be represented by C; Such that
G = 2³
C = 2⁹
Divide C by G

From law of indices, 
Applying this law, we have




Multiply both sides by G


Hence, we can conclude that the correct answer is 64 times Geri’s original answer
 
        
                    
             
        
        
        
-2n-24=-8(2n-4)
Multiply both sides by -1
2n+24=8(2n-4)
Distribute the right side
2n+24=16n-32
Subtract 2n from both sides
24=14n-32
Add 32 to both sides
56=14n
Divide 14 from both sides
n=4
        
                    
             
        
        
        
Answer:
f(-7)=0.
f(2)=-9/5.
f(3) doesn't exist because 3 isn't in the domain of the function. 
Step-by-step explanation:
 is the given function.
 is the given function.
We are asked to find:


 .
.
f(-7) means to replace x in the expression called f with -7:
Evaluate  at
 at 
 
 



So f(-7)=0.
f(2) means to replace x in the expression called f with 2:
Evaluate  at
 at 
  
 



So f(2)=-9/5
f(3) means to replace x in the expression called f with 3:
Evaluate  at
 at 
  
 


Division by 0 is not allowed so 3 is not in the domain of our function.
