Answer:
what is the question
Step-by-step explanation:
 
        
             
        
        
        
You have a function 

.
Since the range of the function 

 is 
![[-1,1]](https://tex.z-dn.net/?f=%5B-1%2C1%5D)
 you have that 

.
Answer: The range of given function is [0,3] and the correct choice is C.
 
        
        
        
Let h = amount of hours

Since they earn $7.50 per hour, we can multiply that by an unknown amount of hours to get $116.25. Let's solve:

Divide both sides by 7.5 to isolate the h, amount of hours.

Simplify.

In conclusion, someone would have to work 15.5 hours to earn $116.25 if they earn $7.50 per hour.
 
        
             
        
        
        
Answer:
x=10  x=-2
Step-by-step explanation:
(x − 3)(x − 5) = 35
FOIL
x^2 -5x-3x+15 = 35
Combine like terms
x^2 -8x+15 = 35
Subtract 35 from each side
x^2 -8x+15-35 = 35-35
x^2 -8x-20 =0
Factor 
What 2 numbers multiply to -20 and add to -8
-10*2 = -20
-10 +2 = -8
(x-10)(x+2) =0
Using the zero product property
x-10 =0  x+2 = 0
x=10  x=-2
