Question

The equation below shows the perimeter f(x) of several rectangular side tables having width x inches: f(x) = 24 + 2x

The perimeter of each table is less than 50 inches. Which of the following best describes the domain of f(x) = 24 + 2x?

a. All integers greater than 0 and less than 13

b. All integers greater and 0 and less than 50

c. All real numbers greater than 0 and less than 13

d. All real numbers greater than 0 and less than 50

Answer 1

24+2x < 50

-24        -24

 

2x < 26

 

Divide out both sides by 2

 

    x < 13

 

     Since an integer can't have a fraction, it would rule out many conceivable lengths;

 

    So, (c)   All Real Number <0 and < 13
