I want to show that
log(2+x)−log(x)<2x
∀x∈R+
I know I need to apply the Mean Value Theorem to find an upper bound of the function to the left and show that it is smaller than 2x, but I can't find the correct upper bound. I've tried multiple variations of the inequality. My teacher also said that I only needed to check in the interval from 0 to 2, but I'm not sure why.
