" The function "f(x)=2+4x^(2)+6x^(4)+8x^(6)" has "

The function f(x) = x^2 - 4x + 6 is

The maximum value of the function f(x)= x^(2)+2x^(2)-4x+6 exits at

Is the function: f(x) = (x^(2) - 8x + 18)/(x^(2) + 4x + 30) one-one?

Express the function f(x) =2x^(4) - 3x^(2) + 6x+7-4 sin x as sum of an even and an odd function.

Express the function f(x) =2x^(4) - 3x^(2) + 6x+7-4 sin x as sum of an even and an odd function.

If the function f(x)=x^(4)+bx^(2)+8x+1 has a horizontal tangent and a point of inflection for the same value of x then the value of b is equal to -1 (b) 1 (c) 6 (d) -6

The function f(x) = 2x^3 - 6x^2 + 6x + 5 has

For x>=0, the smallest value of the function f(x)=(4x^(2)+8x+13)/(6(1+x)), is

The function f(x)=4x^(3)-6x^(2)-72x+30 is strictly decreasing on interval.

Prove that the function f(x) = 2x^3 - 6x^2 + 6x + 5 has no maximum or minimum.
