The answer is D) y = 3x^2 - 2, because the x is squared, making the function a quadratic function. Quadratic functions will be in the shape of a parabola (a u or upside down u). 
Meanwhile any function whose degree (highest exponent of x) is one is a linear function. It will have be a straight line.
        
             
        
        
        
Answer:
3,25-2,5=0,75 it is equal to 3/4 so D
 
        
             
        
        
        
(area of square) - (area of triangle)
We know the are of a square is equal to s^2, where s is the side length. 
While the are of a right angle tringle is 1/2*base*height
Then we have,
s = 10
base = 4
height = 4
(area of square) - (area of triangle)
=> (10^2) - (1/2)(4)(4) 
=> 100 - 8
=> 92
Finally we get: 92 in^2
        
             
        
        
        
The answer is C, you double 8 million and then double 16 million
