use the graph of f to draw the graph of its inverse function. use the graphing tool to graph the function.

Explanation:

Step1: Recall inverse - function graph property

The graph of a function $y = f(x)$ and its inverse $y = f^{-1}(x)$ are symmetric about the line $y=x$.

Step2: Identify key points on the original function

Let's assume some key points on the given line $y = f(x)$. For example, if the line passes through points $(x_1,y_1),(x_2,y_2),\cdots$. The corresponding points on the inverse function will be $(y_1,x_1),(y_2,x_2),\cdots$.

Step3: Reflect points across $y = x$

If we have a point $(a,b)$ on $y = f(x)$, its image on $y = f^{-1}(x)$ is $(b,a)$. Plot these reflected points.

Step4: Draw the inverse - function graph

Connect the reflected points with a straight - line (since the original function appears to be linear) to get the graph of the inverse function.

Answer:

To graph the inverse function, reflect the points of the given function $f(x)$ across the line $y = x$ and then connect the reflected points. Since we can't actually use a graphing tool here, the steps above provide the method to draw the graph of the inverse function.
