Hello, I was trying to draw the graph of a function which answers a little question. But, I ended up with this equation: (x - 1) * (exp(x) + 2) - 1 = 0 I am not able to solve it. I am not sure if we can find an analytical expression. Does someone have an idea? If you want, I can write a docx to show the initial problem and where it appears. Bye
