Chapter 4: Q. 3 (page 241)

True or False : A test number for the interval $- 2 < x < 5$ could be 4.

Short Answer

Expert verified

True.

Step by step solution

Step 1. Given information.

Interval given is $- 2 < x < 5$ or $(- 2, 5)$ .

An interval is a range of numbers between two given numbers and includes all of the real numbers between those two numbers.

As $4$ comes in the interval $(- 2, 5)$ , so it can be a test number for the given interval.
