Draw a cartesian plane, create a graph with the equation x = y^2 - 2
then substitute numbers into the equation so that it is true, to find points on the graph, e.g. substitute y with 1, you get 
x = 1^2 - 2
x = 1 - 2 = -1, so when y = 1, x = -1, this point is (-1, 1)
for the next substitute y with 2,
x = 2^2 - 2
x = 4 - 2 = 2, the point is (2, 2)
you might want to try negative values of y 
y = -1, x = (-1)^2 - 2
x = -1 the point is (-1,-1)
then plot the points on the graph
        
             
        
        
        
Answer:
A
Step-by-step explanation:
look where the plot is Set 1 is at 8 and Set 2 is at 10. obviously 10 is greater than 8
 
        
             
        
        
        
Answer:
<h2>$648.70</h2>
Step-by-step explanation:
30% of 499 is 149.70
499+149.70=648.70
 
        
             
        
        
        
Domain = Set of all real numbers, which is choice B
Range = Choice C) 

The domain is the set of allowed x value inputs of a function. In this case, we can plug in any x value we want. The graph stretches forever in both directions along the x axis. This is shown by the arrows.So that's why the domain is the set of all real numbers.
The range is the set of outputs of a function. It is the set of possible y values. As you can see on the graph, the highest point is at (-1,3) which is the vertex.
The largest y value possible is y = 3. Any other y value smaller than this is possible. So the range is therefore 

 where y is a real number
