The greatest value of `f(x) = (x^2 + x +2) / (x^2 +x+1)` will be

The greatest value of f(x) =2x^2+2//x^2 for -2le x lt 0,0 lt x le 2 and f(0)=1 is

The least and the greatest values of f(x)=x^(2)logx in [1,e] are

The greatest value of f(x)=cos(xe^([x])+7x^(2)3x),xe in[-1,00) is

The greatest value of the function f(x) = x^(2)"log" (1)/(x) is-

The greatest value of f(x)=cos(x e^([x])+7x^(2)-3x), x in [-1,oo) is :

The greatest value of : f(x) =cos[x e^([x])+7x^(2)-3x], x in [-1, oo) is :

The greatest value of f(x)=cos(x e^([x])+7x^2-3x),x in [-1,oo], is (where [.] represents the greatest integer function). -1 (b) 1 (c) 0 (d) none of these

The greatest value of f(x)=sin{x [x]+e^([x])+(pi)/(2)-1} for all x in [0,oo) is

If f(x) = x+ 1/x , x>0 then the greatest value of f(x) is (a) -2 (b)0 (c) 3 (d) none of these

Let f(x) = cos^(2) x + cos x +3 then greatest value of f(x) + least value of f(x) is equal to
