Answer:
C. No, more than one output value x is assigned to the input y-value
Step-by-step explanation:
Given
х      у
-3    -2
3     6
0      7
1       7
2      4
3     - 1
Required
State if the table shows x as a function of y
x being a function of y means

i.e. x represents the output while y represents the input of the function
Note that each value of y (input) must be assigned to separate values of x (output) for a function to be established
Having said; 
Next step: We have to examine the x and y column
In the y column, the value 7 occurred twice (as shown below)
<em>х      у
</em>
<em>0      7
</em>
<em>1       7
</em>
<em />
This implies that;
Input 7 gives output of 0 and 1.
<em>Hence, this is not a function.</em>
<em>Option C answers the question.</em>
 
        
             
        
        
        
Answer:
No
Step-by-step explanation:
No because the 8x^3 is all one term since it is not separated by any signs.
 
        
             
        
        
        
Answer:
n=3.5
Step-by-step explanation:
2²=4
14÷4=3.5
3.5×4=14
3.5×2²=14
 
        
             
        
        
        
You just have to multiply the percentage by the amount:
(150/100)×$63 
1.5×$63= $94.50
If you aren't allowed a calculator, then just find half of $63 (the 0.5 of the fraction) and add it to $63 (the 1. of the fraction).
$63÷2= $31.5
$63+$31.5= $94.50
        
                    
             
        
        
        
F(-1)=2
F(2)=-1
F(3)=-3
The f(x) part is the input and the stuff after is the output
