SUMMARY

The limit of the function e^(1/(6-x)) as x approaches 6 from the right is definitively 0. This conclusion is reached by analyzing the behavior of the term 1/(6-x), which approaches negative infinity as x approaches 6 from the right. Consequently, e raised to a negative infinity results in 0. Any reference to the limit being e^(17/3) is incorrect, confirming that the book's answer is erroneous.

PREREQUISITES
  • Understanding of limits in calculus

lim e^(1/(6-x))
x->6+

Was wondering how to solve for this limit analytically. I plotted it and see it going to 0, but that is not the answer in the book.

Hello tsaitea. Welcome to PF !

What is \displaystyle \lim_{x\to6^{+}}\,\frac{1}{6-x}\ ?
 
oh -infinity, but the answer is e^(17/3)?, maybe the book is wrong then?

Actually \displaystyle \ \ \lim_{x\to6^{+}}\,\frac{1}{6-x}=-\infty\ .

If the problem you were given was to find \displaystyle \ \ \lim_{x\to6^{+}}\,e^{1/(6-x)}\,,\ then the book is wrong if it gives the answer as e^(17/3) . You were right in your original post to say the answer is zero.
 
Okay, thanks so much!
