f(-1) = -11 and f(3) = -3 . these functions are true . 
What does a math function mean?
- A relationship between a group of inputs and one output each is referred to as a function.
-   A function is an association between inputs in which each input is connected to precisely one output.
-  A domain, codomain, or range exists for every function. f(x), where x is the input, is a common way to refer to a function.
- In mathematics, a function is an expression, rule, or law that establishes the relationship between two variables (the dependent variable).
given function  f(x) = 2x - 9
    f(-1) = -11 ⇒ x = -1 put in function
                        f( -1 ) = 2 * -1 - 9  ⇒ - 11
     f(2) = 5   ⇒ x = 2 put in function
                     f( 2 ) = 2 * 5 - 9 = 1
     f(3) = -3  ⇒  x = 3 put in function
                      f ( 3 ) = 2 * 3 - 9 = -3
        f(-3) = 15   ⇒  x =  -3 put in function
                      f( -3) = 2 * -3 - 9 = - 15

Answer:
x = 71/5  (as an improper fraction)
x = 14 1/5 (as a proper fraction
x = 14.2 (as a decimal)
Step-by-step explanation:
It's a rectangle so the diagonals are equal
7x - 9 = 2x + 62
Subtract 2x from both sides
5x - 9 = 62
Add 9 to both sides
5x = 71
Divide both sides by 5
x = 71/5  (as an improper fraction)
x = 14 1/5 (as a proper fraction
x = 14.2 (as a decimal)
 
        
                    
             
        
        
        
I am pretty sure that it is table one because each number from the original recipe to the teachers recipe is multiplied by three.
        
             
        
        
        
Answer:
<u>77</u> is the quotient of 1,078 and 14.
Step-by-step explanation:
quotient is the answer to a division problem.
numerator/denominator = quotient
1,078/14 = quotient
1,078/14 = <u>77</u>
