Answer:
 ![(-9,16]](https://tex.z-dn.net/?f=%28-9%2C16%5D)
Step-by-step explanation:
we know that
The domain of x is equal to the interval--------> ![(-2,3]](https://tex.z-dn.net/?f=%28-2%2C3%5D)

All real numbers greater than  and less than or equal to
 and less than or equal to 
Let

For 

For 

so
The range of the function is the interval--------> ![(-9,16]](https://tex.z-dn.net/?f=%28-9%2C16%5D)
 
        
                    
             
        
        
        
Answer:
The solutions to the quadratic equations are:

Step-by-step explanation:
Given the function

substitute y = 0 in the equation to determine the zeros

Switch sides

Add 4 to both sides

Simplify

Rewrite in the form (x+a)² = b
But, in order to rewrite in the form x²+2ax+a²
Solve for 'a'
2ax = -6x
a = -3
so add a² = (-3)² to both sides


Apply perfect square formula:  (a-b)² = a²-2ab+b²


solve

Add 3 to both sides

Simplify

now solving

Add 3 to both sides

Simplify

Thus, the solutions to the quadratic equations are:

 
        
             
        
        
        
The unit rate is 12.65 per hour.
