Chapter 4: Q. 23 (page 245)

Use the Intermediate Value Theorem to show that each polynomial function has a zero in the given interval.
$f (x) = 3 x^{3} - x - 1; [0, 1]$

Short Answer

Expert verified

The given function has a zero between 0 and 1

Step by step solution

Step 1. Given Information

The given function and the interval is $f (x) = 3 x^{3} - x - 1; [0, 1]$

Step 2. Calculation

We will evaluate the function at 0 and 1.

$f (0) = 3 {(0)}^{3} - 0 - 1 = - 1 f (1) = 3 {(1)}^{3} - 1 - 1 = 1$

Since, $f (0) < 0 a n d f (1) > 0 a n d f (0) a n d f (1)$ are of opposite sign, it follows from the intermediate value theorem that the function has a zero between 0 and 1.
