A function whose graph can be drawn without lifting the pen is:
AContinuous
BDiscontinuo
CUndefined a
DIncreasing a
Answer & Solution
Correct answer: A. Continuous
1. Continuity is about the graph having no break.
2. A break forces the pen off the paper.
3. So an unbroken graph means the function is continuous.
4. The answer is continuous.
