If Show that f is continuous at x = 1.

Question

Philoid · Accepted Answer

Given:

For f(x) is continuous at x = 1

If f(x) to be continuous at x = 1,we have to show, f(1)^–=f(1) ⁺ = f(1)

LHL = f(1)^– =

(a–b)² = a²–2ab + b²

...(1)

RHL = f(1) ⁺ =

20² + 0 +

...(2)

From (1) & (2),we get f(1)^– ₌ f(1) ⁺

Hence ,f(x) is continuous at x = 1
