Question

What is negative infinity plus a number?

A) Negative Infinity
B) Undefined
C) Infinity
D) The number itself

Answer 1

When you add a number to negative infinity, the result is undefined because negative infinity represents a value that is infinitely negative.

Step-by-step explanation:

When you add a number to negative infinity, the result is undefined.

This is because negative infinity represents a value that is infinitely negative, while the number you are adding represents a specific value. The two cannot be combined in a meaningful way.

For example, if we have −∞ + 5, the result is undefined because we cannot determine what the sum of negative infinity and 5 would be.
