Answer:
D
Step-by-step explanation:
This questions asks use to find what f(x) or y is, when x is equal to -2. 
So, substitute -2 in for x in the equation. 
f(x)=2(4)^x 
f(-2)=2(4)^-2 
Evaluate the exponent. Negative exponents follow this rule: 
b^-x= 1/b^x 
We have 4^-2. This will become 1/4^2 or 1/16 
f(-2)=2(1/16) 
Multiply 
f(-2)=2/16 
This fraction can be simplified. Both the numerator (top number) and denominator (bottom number) can be divided by 2. 
f(-2)=2/2 / 16/2 
f(-2)= 1/8 
The correct choice is D. 1/8
 
        
             
        
        
        
Answer:
domain: [-3,2]
range: [-3,2]
Step-by-step explanation:
domain: all possible x values *maximum values of x
range: all possible y values *maximum values of x
brackets means the max while parenthesis mean infinite
 
        
             
        
        
        
You have 

 apples left. 
You have 5 whole apples, you took one whole apple out, which equals 4 whole apples left. Then with the whole apple you took out, you ate 

 of it. 
Jack ate  of an apple in 5 apples.
 of an apple in 5 apples. If you say that Jack ate 

 of 3 apples, then he ate 

 apples. So there isn't any difference when he ate 

 of an apple.
 
        
        
        
Answer:
answer  choice D
Step-by-step explanation:
 x => 6 - 4x > 18
= 6-18 > 4x
= - 12 > 4x
= -3 > x
= x < -3
