Answer:
Up on the left, up on the right
Step-by-step explanation:
The given function is:

The degree of f(x) is 4 i.e. an even degree and the leading coefficient i.e. coefficient with highest powered variable is positive in sign.
The graph of a function with even degree always open on same side from both ends. This depends on the sign of leading coefficient what will be the direction of both ends. The positive sign indicates upward opening and negative sign indicates downward opening. 
Since, the leading coefficient of f(x) is positive, it will open towards up from both right and left side. So, the correct option is the fourth option.
 
        
             
        
        
        
Answer:
8/3ft
Step-by-step explanation:
To find how high she would bounce, we need to first understand that her height of each jump would be multiplied by 2/3 given that each bounce afterwards is two thirds as high as the bounce before.
We can then set the equation:
6 x 2/3 x 2/3 
=6 x (2/3)^2
=8/3
Therefore the answer is 8/3 ft.
Hope it helps!
