Suppose that f'' and g'' exist and that f and g are concave up for all x. Are the statements below true or false. If true explain if false give an counter example.

1. f(x) + g(x) is concave up for all x
2. f(x) - g(x) cannot be concave up for all x

What is the derivative of the function F(x)=x^x with respect to x?

I would at first think it would be x*x^(x-1)=x^x, but I don't think it is.

Please tell me if the expression below are true or false and why??

1.the 100th derivative of sinh x is coshx
2.the function tanh x is odd, that is, tanh(-x) = -tanh x
3.the only functions whose fourth derivatives are equal to cos t are
of the form cos t + C, where C is any constant.
4.if y satisfies the equation y^2 + xy - 1 = 0, then dy/dx exists every
where
5.if the derivative of f(g(x)) is equal to the derivative of f(x) for all x,
then g(x) = x for all x
