Consider the function f(x)=6/(x-2).
To find out the sets of possible input and output values of the function, Clare created a table and evaluated f at some values of x. Along the way, she ran into some trouble.
1. Find f(x) for each x-value Clare listed.
Describe what Clare’s trouble might be.
2. Use graphing technology to graph function f. What do you notice about the graph?
3. Use a calculator to compute the value you and Clare had trouble computing. What do you notice about the computation?
4. How would you describe the domain of function f?
