Question

use a calculator to evaluate the function at the indicated value of x. round your result to three decimal places. function value f(x) = 5 ln(x) x = 0.91

Answer 1

The value of the function f(x) = 5 ln(x) at x = 0.91, rounded to three decimal places, is -0.472.

Step-by-step explanation:

To evaluate f(x) = 5 ln(x) at x = 0.91, we can follow these steps:

Substitute x = 0.91 into the function:

f(0.91) = 5 ln(0.91)

Use a calculator to calculate the natural logarithm of 0.91:

ln(0.91) ≈ -0.095

Multiply the result by 5:

f(0.91) ≈ 5 * (-0.095) ≈ -0.475

Round the answer to three decimal places:

f(0.91) ≈ -0.472

Therefore, the value of f(x) = 5 ln(x) at x = 0.91, rounded to three decimal places, is -0.472.
