Chapter 14: Q. 14 (page 876)

In Problems 7–16, use a table to find the indicated limit.

14.limx→0ex-e-x2.

Short Answer

Expert verified

limx→0ex-e-x2=0.

Step by step solution

01

Step 1. Given.

Given a function f(x)=ex-e-x2 whose limit needs to be found tending to 0.

02

Step 2. The table is as follows.

Compare the given function 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 close to 0 then f(x) gets close to 0.

So,limx→0ex-e-x2=0.
