# Electric Potential Integral Question Confused

E=KQ/R^2

## The Attempt at a Solution

I'm kinda confused at what the question is asked. It is in terms of x, but I thought the integral for potential is V=int(Edr)? Also, should it be integration starting from infinity? Why is the integration from -2 to 3?. I'm just confused by the wording...

Potential due to a point charge is given by
V=Kq/R
You can use this to write potential due to a small element and then integrate.
