01) The points of discontinuity of the function :
f(x) = (2x^2 + 6x - 5) are :
(12x^2 + x -20)
(a) -4/5 and 5/3
(b) -4/3 and 5/4
(c) 4/5 and -5/3
(d) 4/3 and -5/4
02) A function f(x) is defined as follows :
x When x < 1
f(x) { 1+ x when x >1
3/2 when x = 1
03) Then f(x) is :
(a) Discontinuous at x = 1
(b) Undefined at x = 1/2
(c) Continuous at x = 1
(d) None of these
04) lt 6x + 8x e^x
x→0 log (1 + 2x)
(a) 7
(b) 14
(c) 4
(d) None
05) lim x^n - 2^n =80 and n∈N,then :
x→2 x - 2
(a) n = 5
(b) n = 0
(c) n = 4
(d) None
06) If f(x) = {(x^2 + k(1 - x) - 2x) / x - 2}
and f(x) = 2 if x = 2
is continuous at x = 2 then k =
(a) 0
(b) -1
(c) 1
(d) 2
