Question

Need help plz what is a hole

Answer 1

Answer:

Statements 1,4&5

Step-by-step explanation:

A hole is when both, numerator and denominator, of a fraction become 0 (zero).

This would happen when the numerator and denominator have a common factor.

Example:

(2x+4)/(x+2)

= [2(x+2)]/(x+2) = 2

Although the fraction can be simplified, there's a hole at x = -2.

x = -2 will not be part of the domain.

The hole is represented by an open circle.
