If the point `(2,k)` lies outside the circles `x^2+y^2+x-2y-14=0a n dx^2+y^2=13" then k"` lies in the interval `(-3,-2)uu(3,4)` (b) `(-3,4)` (c) `(-oo,-3)uu(4,oo)` (d) `(-oo-2)uu(3,oo)`

If the point (2,k) lies outside the circles x^2+y^2+x-2y-14=0a n dx^2+y^2=13" then k" lies in the interval (a) (-3,-2)uu(3,4) (b) (-3,4) (c) (-oo,-3)uu(4,oo) (d) (-oo-2)uu(3,oo)

If the point (2,k) lies outside the circles x^(2)+y^(2)+x-2y-14=0andx^(2)+y^(2)=13 then k lies in the interval (-3,-2)uu(3,4)(b)(-3,4) (c) (-oo,-3)uu(4,oo)(d)(-oo-2)uu(3,oo)

If the point (lambda,lambda+1) lies inside the region bounded by the curve x=sqrt(25-y^(2)) and y-a xi s, then lambda belongs to the interval (-1,3)( b) (-4,3)( c) (-oo,-4)uu(3,oo)(d) none of these

If the point (lambda,lambda+1) lies inside the region bounded by the curve x=sqrt(25-y^2) and y-a xi s , then lambda belongs to the interval (-1,3) (b) (-4,3) (c) (-oo,-4)uu(3,oo) (d) none of these

If the function f(x)=2x^2-k x+5 is increasing on [1,\ 2] , then k lies in the interval (a) (-oo,\ 4) (b) (4,\ oo) (c) (-oo,\ 8) (d) (8,\ oo)

If a point (a,2) lies between the lines x-y-1=0 and 2(x-y)-5=0 , then the set of values of a is (A) (-oo,3)uu(9/2,oo) (B) (3,9/2) (C) (-oo,3) (D) (9/2,oo)

If a point (a,2) lies between the lines x-y-1=0 and 2(x-y)-5=0, then the set of values of a is (A) (-oo,3)uu((9)/(2),oo) (B) (3,(9)/(2)) (B) (-oo,3) (D) ((9)/(2),oo)

The function f (x) = 2x^(3) - 15 x ^(2) + 36 x + 6 is strictly decreasing in the interval a) (2,3) b) (-oo,2) c) (3,4) d) (-oo,3) uu(4,oo)

If the function f(x)=2x^(2)-kx+5 is increasing on [1,2], then k lies in the interval (a) (-oo,4)(b)(4,oo)(c)(-oo,8)(d)(8,oo)

If the line 2x-2y+lambda=0 is a secant to the parabola x^(2)=-8y, then lambda lies in the interval (4,oo)(b)(-oo,4)(c)(0,4)(d)Noneofthese
