f(x)=  sqrt(e^x-1) / sqrt(e^x-2)

I cannot solve this one : e^x-2>0

Simplifying e * x + 2 = 0 Multiply e * x ex + 2 = 0 Reorder the terms: 2 + ex = 0 Solving 2 + ex = 0 Solving for variable 'e'. Move all terms containing e to the left, all other terms to the right. Add '-2' to each side of the equation. 2 + -2 + ex = 0 + -2 Combine like terms: 2 + -2 = 0 0 + ex = 0 + -2 ex = 0 + -2 Combine like terms: 0 + -2 = -2 ex = -2 Divide each side by 'x'. e = -2x-1 Simplifying e = -2x-1

 

i think its right.
