No. A function maps one input to exactly one output. The given relation maps 1 to both 1 and -1, as indicated by the pairs (1, 1) and (1, -1).
 
        
             
        
        
        
Answer:
y = x^2 (x - 2) = x^3 - 2 x^2
dy/dx = 3 x^2 - 4 x
At x = 3  dy/dx = 3 * 9 - 4 * 3 = 15   The slope (gradient) of the curve
 
        
             
        
        
        
Answer:
The acceleration is 

Step-by-step explanation:
Use the equation of motion,

where u=0m/s is the initial speed, v=9m/s is the final speed and t=2 seconds is the time.
We substitute the values into the equation and solve for the acceleration, a 

This means that;

Divide both sides by 2 to get:
