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.
