It has been at least 5 years since my last math class and I am kinda struggling.(adsbygoogle = window.adsbygoogle || []).push({});

The question is:

Use the intermediate value theorem to show that there is a root of ln x = e^-x on the interval (1,2). Find the correct root to 3 decimal values

What i have so far

f(1) = ln 1 - e^-1 = 0 which -.368< 0

f(2) = ln 2 - e^-2 = 0 which .558 > 0

am I doing this correct or am I really off base ?

thanks joe
