Chapter 5: Q. 39 (page 284)

In Problems 33-40, the graph of an exponential function is given. Match each graph to one of the following functions.

Short Answer

Expert verified

The function is y=3x-1and matches to (e)

Step by step solution

01

Given information

Given graph

02

Checking the graph and forming the function  

(1,2),(0,0)The graph is increasing and has a horizontal asymptote of y=-1

The graph contains the points , and (-1,-23)

This means that the graph has a one-unit shift downward of the function y=3x

Thus, the graph must be that of y=3x-1so the answer is OptionE

Foreign ExchangeTraders often buy foreign currency in hope of making money when the currency鈥檚 value changes.

For example, on March 22, 2011, one U.S. dollar could purchase 0.7045 Euros, and one Euro could purchase 114.9278 yen. Let fxrepresent the number of Euros you can buy with xdollars, and let gxrepresent the number of yen you can buy with xEuros.

(a) Find a function that relates dollars to Euros.

(b) Find a function that relates Euros to yen.

(c) Use the results of parts (a) and (b) to find a function that relates dollars to yen. That is, find g鈭�fx=gfx

(d) What is gf1000? Interpret this result.
