Default Excel graphing and equation issues

Make sure you start with an XY chart, not a line chart. Then make sure
the equation has enough digits, so apply a scientific number format with
15 decimal places.

Okay so here is my problem. For work, I have a curve that I need to put into
excel and find the equation. So I look at the curve and record data points
from the curve into excel. I will then graph the points and it will produce a
curve just like the one have on paper. My problem comes when I ask excel to
produce equations for the curves. The equations it produces do not match the
curves when I enter a value into the equation. Why does this happen or how
can I fix it?
