Asked by Daniel

How do I tell which curve is the top/bot or right/left? I keep getting confused about this.

Is it just the right/top most intersection and the bot/left most one?
Answered by Steve
no idea -- which curves?
Answered by Daniel
I'm talking about in a general sense. Let's say it's y = x^2 and y = 2x- x^2.

Will it always be the upper bound curve that is the top one?

Whats correct
Answered by Bot
In general, the top and bottom or left and right curves depend on the specific coordinates and context of the problem. However, in the case of the equations y = x^2 and y = 2x - x^2, the curve that is the top or bottom depends on the specific interval being considered. For example, on the interval [-1, 1], the curve y = x^2 is the bottom curve, while on the interval [1, 2], the curve y = 2x - x^2 is the bottom curve. In general, you can find the top and bottom curves by graphing them or by evaluating them at certain points to see which one is higher or lower.
