If `f(x)=a-(x-3)^(8//9)`, then the maximum value of `f(x)` is

The maximum value of f(x)=x^(2/x) is:

The maximum value of f(x)=-|x+2|+5 is:

Let f(x)=x^(3)e^(-3x),x>0. Then the maximum value of f(x) is

The maximum value of f(x)=(x-2)(x-3)^2 is

If f(x)=3x^(3)-9x^(2)-27x+15 ,t hen the maximum value of f(x) is

If f(x)=|x-1|+|x-2|-|x-3|, then (a) maximum value of f(x) is 3 if x in[2,3] (b) maximum value of f(x) is -3 if x in[1,3] (c) maximum value of f(x) is -3 if x in[1,2] (d) maximum value of f(x) is 3 if x in[1,3]
