Capping Percentage at 100% within Trend Formula

I am currently forecasting percentages for future dates for work going up and down, but when I use the Trend formula the percentages either go over 100% or below 0% into a negative.

I know that there is the Min function to cap it, but I can't quite get this to work the way that I want and I can't really find any other alternatives.

Example below

Formula
=TREND($A$8:C8,$A$7:C7,D7)
