The potential energy of a particle on the x-axis is given by U+ 8xe ^-xsquared/19 where x is 1 meter and U is in Joules. Please find the point on the x-axis for which the potential is a maximum or minimum. I've worked it three times and I get these three answers. Which one is correct?

4.359 m

3.082 m

1.202 m
