hi can u explain the line " as both e^2x and x² is more than 0, 2x-1 is less than 0" ?
X^2 is always positive as any number ( positive or negative) will always ended up positive when squared. Eg square of -2 is 4, and so on. By the way this is a very useful fact that is often used.
e is positive number ( e = 2.718). There is thus no value of x that can make e^2x negative.
Hope this helps
