Few problems along with their solutions from this chapter are given follows:
Question:
Examine the continuity of the function f (x) = x^{3} + 2x^{2}  1 at x = 1.
Solution:
Question:
An example of a function which is continuous everywhere but fails to be differentiable exactly at two points is ........ .
Solution:
An example of a function which is continuous everywhere but fails to be differentiable exactly at two points is x + x – 1. The functions is continuous everywhere but fails to be differentiable exactly at two points x = 0 and x = 1.
Question:
If f is continuous on its domain D, then  f  is also continuous on D.
Solution: True
If a function is continuous on its domain, then the modulus of the function is also continuous in the same domain.
Hence,  f is also continuous on D.
Question:
The composition of two continuous functions is a continuous function.
Solution: True
The composition of two continuous functions is also a continuous function
Question:
Trigonometric and inverse trigonometric functions are differentiable in their respective domain.
Solution: True
All the trigonometric and inverse trigonometric functions are differentiable in their respective domain.
