Whenever you see <em>x </em> next to a 3, and it says that it equals 9, you know that 3•3=9.
        
                    
             
        
        
        
Answer:
(6,4)
Step-by-step explanation:
The equation is in 'point-slope' form. 

This means we can identify the point that was used in the equation. 

(6,4) would be a solution to the equation given. 
Hope this helps.
 
        
             
        
        
        
Answer:
The first one
Step-by-step explanation:
g(x) = ax² + bx + c
Point (0,0):
0 = a.0² + b.0 + c
c = 0
Point (2,1):
1 = a.2² + b.2 + c
4a + 2b + c = 1
But c = 0. Then:
4a + 2b = 1
Another point: (- 2, 1):
1 = a.(- 2)² + b.(- 2) + c
4a - 2b = 1
{4a + 2b = 1
{4a - 2b = 1
4a + 2b = 4a - 2b
4a - 4a = - 2b - 2b
- 4b = 0
b = 0
4a + 2b = 1
4a + 2.0 = 1
4a = 1
a = 1/4
The formula is:
g(x) = (1/4)x²
I hope I've helped you.
