If `f(x)=(x)/(x^(2)+1)` is increasing function, then the value of x lies in

If =(x)/(x^(2)+1) is increasing function, then the value of x lies in

For which values of x, the function f(x)=(x)/(x^(2)+1) is increasing and for which value of x, it is decreasing.

For which values of x, the function f(x)=(x)/(x^(2)+1) is increasing and for which values of x, it is decreasing.

If f(x)=x^(3)-6x^(2)+9x+3 is a strictly increasing function ,then x lies in :

If f(x) = x^(2) e^(-x^(2)/a^(2) is an increasing function then (for a gt 0) , x lies in the interval

If f(x) = x^(2) e^(-x^(2)/a^(2) is an increasing function then (for a gt 0) , x lies in the interval

Show that the function f(x)=x^(7)+8x^(5)+1 is increasing function for all values of x.

The function f(x)=(x)/(x^(2)-1) increasing, if

If f(x) = x^(2) + kx + 1 is increasing function in the interval [ 1, 2], then least value of k is –
