In Problems 7–16, use a table to find the indicated limit.
Given function is whose limit tends to 0 is need to be found.
Compare the given limit to .
Choose values of x close to 0 , arbitrarily starting with -0.01. Then we select additional numbers that get closer to 0 , but remain less than 0 .
Next choose values of x greater than 0 , staring with 0.01, which get closer to 0 .
Finally evaluate f(x) at each choice to obtain the required Table.
As x gets closer to 0 then f(x) gets closer to 2.
