Chapter 5: Q. 74 (page 315)

Use a graphing utility to solve each equation. Express your answer rounded to two decimal places.
$e^{- x} = - \ln x$

Short Answer

Expert verified

The solution of the given equation is 0.57.

Step by step solution

Step 1. Given information.

The given equation is:

$e^{- x} = - \ln x$

Step 2. Determine the solution by the graphing utility.

Plot the graphs of $y_{1} = e^{- x}$ and $y_{2} = - \ln x$ on a coordinate plane. The x-coordinate of the intersection point is the solution of the given equation.

The graphs intersect each other at $x \approx 0.567$ . After rounding the value to two decimal places $x \approx 0.57$ .

Step 3. Conclusion.

The solution of the given equation is 0.57.
