Have you ever been at the grocery store and stood, staring, at two different sizes of the same item wondering which one is the better deal? If so, you are not alone. A UNIT RATE could help you out when this happens and make your purchasing decision an easy one.
In this lesson, you will learn what UNIT RATES are and how to apply them in everyday comparison situations. Click the links below and complete the appropriate sections of the Unit Rates handout.

Answer:
   (a)  h(x) = 1/2x -1/2
Step-by-step explanation:
The inverse of the function y = f(x) is found by solving x = f(y).
__
<h3>setup</h3>
   x = f(y)
   x = 2y +1 . . . . . . use the definition of f(x)
<h3>solution</h3>
   x -1 = 2y . . . . . subtract 1
   (x -1)/2 = y . . . . divide by 2
   y = 1/2x -1/2 . . . . eliminate parentheses
   h(x) = 1/2x -1/2 . . . write in functional form
The inverse of f(x) = 2x+1 is ...
   h(x) = 1/2x -1/2
