Given the function f (x) = - e ^ x, G (x) = LNX, e is the base of natural logarithm

Given the function f (x) = - e ^ x, G (x) = LNX, e is the base of natural logarithm

Let f (x) = g (x) - f (x) = LNX + e ^ x > 0
F '= (1 / x) + e ^ x > 0, f (x) is a monotone increasing function
x→0+ F(0+)→ -∞ 0
There exists x0 ∈ (0,1) f (x0) = 0, that is, the equation f (x) = g (x) has a unique real root
