08.11.2021 · Continuity Defination. The term 'continuity' is derived from the word continuous, which means an endless or unbroken path. Continuity of a function: This term can be better understood if defined in terms of limits.A real function f(x) can be considered as continuous at a point say, x = c, if the function f(x) is approaching to c is f(c).

Nov 08, 2021 · Geometrical Representation of Continuity. Example of Continuity. Question: Show that f(x) is continuous at x=4 for the function f(x) = (x2-2x)/ (x-3) Solution: Given function f(x) = (x2-2x)/ (x-3) Substituting f(x) at x = 4, i.e., f(4) = (42-2(4))/ (4-3) We get the answer as 8. Since, we get the result as 8 for x = 4, i.e., f(4) = f(x)

Example: Consider the function \(f(x)=(2x-3)^{\frac{1}{5}}\).Discuss its continuity and differentiability at \(x= \frac{3}{2}\). Solution: For checking the continuity, we need to check the left hand and right-hand limits and the value of the function at a point x=a. L.H.L. = \(\lim\limits_{x \to a^{-}}f(x)= \lim_{x \to \frac{3}{2}}(2x-3)^{\frac{1}{5}}\)
