Answer:
if you meant x squared the answer is 3x^2
Step-by-step explanation:
If f(x) is equal to 2x you can substitute x squared for f(x) and that would be x squared+x squared+x squared which is 3x^2
 
        
                    
             
        
        
        
1/3 is in fact NOT larger than 4/5. 4/5 is larger than 1/3.
        
                    
             
        
        
        
Last one and first. You can find out why by isolating the cube root and cubing both sides.
        
                    
             
        
        
        
Answer:
two real, unequal roots
Step-by-step explanation:
y is definied as y = 3x - 1.  Substitute 3x - 1 for y in xy = 9, obtaining:
x(3x - 1) = 9.  Then:
3x^2 - x - 9 = 0.  In this quadratic, the coefficients are a = 3, b = -1 and c = -9.
Calculating the discriminant b^2 - 4ac, we get (-1)^2 - 4(3)(-9), or 1 + 108, or 109.  Because the discriminant is positive, we have two real, unequal roots.
