What is the integral of a function of x when x is itself a function of y with respect to x?
Mrkbh
If x = g(y)
∫ f(x) dx = ∫ f(g(y))g'(y) dy
This is called change of variables.

What is a function that is symmetric with respect to the x axis?
The only function that can be symmetric about the x-axis is the x-axis itself. For each value of x a function, f(x), can have at most one value for f(x). Otherwise it is a mapping or relationship but not a function.

How do you explain negative integral?
The definite integral of a function: y = f(x) from x = a to x = b is equal to the area between the function curve and the 'x' axis from x = a to 'x' = b.
