What was the Consumer Price Index for food and beverages in 2006?
Given:
The Consumer Price Index for food and beverages in 2007 was 203.3 after a hefty 3.9% increase from the previous year.
Concept Used:
An addition equation shows the sum of two numbers using + and = signs. The equals sign (=) means the things to its left are equal to the things to its right. The plus sign (+) shows you what things to add.
Calculation:
The Consumer Price Index for food and beverages in 2007 was = 203.3

Find the local minimum and maximum point(s) of f(x), and write them in the form (a, b), specifying whether each point is a minimum or maximum. Coordinates should be kept in fractions. Additionally, provide in your answer if f(x) has an absolute minimum or maximum over its entire domain with their corresponding values. Otherwise, state that there is no absolute maximum or minimum. As a reminder, ∞ and -∞ are not considered absolute maxima and minima respectively.arrow_forward
