Exponential formulas

[Dean76]

Hi,

I am trying to extrapolate data from a graph with an exponential trendline using the trendline formula - but am no sure how to write the equation in a cell.

As you can see from the graph, the formula for the trendline is

How do i represent this in a cell?

I am wanting an exact value for 2021 - I have tried =0.0002*EXP(0.0074*2021) however this gives a value of 625.28 - which, looking at the graph is clearly incorrect.

Am I missing something?

Thanks

Ignore this question -have realised it is an issue with my knowledge of mathematics rather than my knowledge of excel...... (and I don't know how to delete the question......)
