EXERCISE - 1.1 Q-1:
Check each and every relation whether the following are symmetric, reflexive and transitive:
(i) The relation R of the set S = {2, 3, 4, 5, 6, 7, 8, 9 ........ 15} is defined as R = {(a, b): 2a - b = O}
(ii) The relation R of the set S having natural numbers is defined as R = {(a, b): b = 2a + 6 and a < 5}
(iii) The relation R of the set S = {2, 3, 4, 5, 6, 7} is defined as R = {(a, b): b is divisible by a}
(iv) The relation R of the set S having only the Integers is defined as R = {(a, b): a - b is an integer}

Class 12 NCERT Mathematics Chapter 5 Continuity and Differentiability Solutions


Q2: Examine the continuity of the function f(x) = 2x2 -1 at x = 3.
Sol: The given function is f(x) = 2x2-1
At x = 3, f(x)=f(3) =2x 3A(A{2}}-1=17
limx_,3f(x) = limx➔3(2x2 -1) = 2 x 3' -1 = 17
therefore limx_,3f(x) = f(3) Thus, f is continuous at x = 3
