Problem 74
Question
How can a graphing utility be used to visually determine if two functions are inverses of each other?
Step-by-Step Solution
Verified Answer
A graphing utility can be used to determine visually if two functions are inverses of each other by graphing them along with the line \( y = x \). If the graphs of the two functions are symmetrical about the line \( y = x \), then they are inverses of each other.
1Step 1: Plot Function Graphs
Use a graphing utility to plot the graphs of the two functions being considered. Make sure to cover the same interval on the x-axis for both functions.
2Step 2: Plot Identity Line
Plot the line \( y = x \) on the same graph. This line is the line of symmetry for inverse functions.
3Step 3: Identify Symmetry
Visually examine the graph. If the graphs of the two functions are reflections of each other across the line \( y = x \), then they are inverses of each other.
