Yes- it’s not using a curve. I’m not sure why you’d need a curve for exp when you’re intending to use a flat equation.
If you absolutely need it to be a curve asset, your best bet will be to manually make a shape that resembles it.
I checked the curve source files, but couldn’t find an easy in. It’s all heavily tied into the editor- they aren’t meant to allow raw equations. The only way I can think of doing it would be jank and not at all worth it.
