The interval in which y=x^2""e^(-x) is increasing is (A) (-oo,""""oo) (B) ( 2, 0) (C) (2,""""oo) (D) (0, 2)

The interval in which y=x^(2)backslash e^(-x) is increasing is (A)(-oo,oo)(B)(2,0)(C)(2,oo)(D)(0,2)

The interval in which y=x^2e^(-x) is increasing is a) (0,2) b) (-2,0) c) (2,oo) d) (-oo,oo)

If f(x)=int_(0)^(x)log_(0.5)((2t-8)/(t-2))dt , then the interval in which f(x) is increasing is (a) (-oo,2)uu(6,oo) (b) (4,6) (c) (-oo,2)uu(4,oo) (d) (2,6)

The interval in which the function f given by f(x) = x^2 e^(-x) is strictly increasing is (a) ( -oo , oo ) (b) ( -oo , 0 ) (c) ( 2 , oo ) (d) ( 0 , 2 )

The differentiable function y= f(x) has a property that the chord joining any two points A (x _(1), f (x_(1)) and B (x_(2), f(x _(2))) always intersects y-axis at (0,2 x _(1) x _(2)). Given that f (1) =-1. then: The largest interval in which y =f (x) is monotonically increasing, is : (a) (-oo,(1)/(2)] (b) [(-1)/(2),oo) (c) (-oo, (1)/(4)] (d) [(-1)/(4), oo)

f(x) = x^2 increases on: (a) ( 0,oo) (b) (-oo,0) (c) (-7,-3) (d) (-oo,-3)
