F(x) = x^2 - 3x - 7
f(-3) = (-3)^ 2 - 3(-3) - 7
f(-3) = 9 + 9 - 7
f(-3) = 18 - 7
f(-3) = 11
        
             
        
        
        
Here is an example:
Josh bought 7 apples for $21. 
21/7 is 3, so one apple costs $3. This is the unit rate. 
21/7 simplifies to 3/1, that’s another way to think about it. Simplify the fraction until the denominator is 1. 
Hope this helps! Tell me if you have any questions!
