Chapter 2: Problem 51

How can a graphing utility be used to visually determine if two functions are inverses of each other?

Short Answer

Expert verified
To use a graphing utility to determine if two functions are inverses, graph both functions along with the line y = x. If the two functions are mirror images of each other with respect to the y = x line, then they are inverses of each other.

Step by step solution

01

Graph the two functions

First, draw the graphs of the two given functions using a graphing utility. Input the formula for each of the functions to get their respective graphs.
02

Draw the line y = x

Graph the line y = x. This line serves as the mirror for the reflection of one function to its inverse.
03

Compare the graphs

Look at the graphs of the two functions and their relation to the y = x line. If one function is the reflection of the other across the y = x line, then the two functions are inverses of each other.

You will be developing functions that model given conditions. Describe one advantage of using \(f(x)\) rather than \(y\) in a function's equation.

Give an example of an equation that does not define \(y\) as a function of \(x\) but that does define \(x\) as a function of \(y .\)

Begin by graphing the standard cubic function, \(f(x)=x^{3} .\) Then use transformations of this graph to graph the given function. $$ g(x)=x^{3}-2 $$

What must be done to a function's equation so that its graph is reflected about the \(x\) -axis?

Begin by graphing the square root function, \(f(x)=\sqrt{x} .\) Then use transformations of this graph to graph the given function. $$ g(x)=\sqrt{x}+1 $$
