If `y = x^3 - ax^2 + 48x + 7` is an increasing function for all real values of `x,` then `a` lies in

condition that f(x)=x^(3)+ax^(2)+bx^(2)+c is anincreasing function for all real values of x' is

" If "sin^(-1)(sin4)+x^(2)>" ax for all real values of "x" then "a" lies in "

If y=x^3-ax^2+12x+5 is increasing for all values of x, then a lies between K_1 and K_2 then |K_2-K_1|

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

If f(x)=x^(3)-ax^(2)+48x+7 is increasing then a lies between

For all real values of x, increasing function f(x) is

The function f(x)=2ax^(3)+3x^(2)+6(a-1)x+1 is decreasing for all real values of x .Then the greatest integral value of a is
