Applying a polynomial equation in a virtual feed process

I’d like to apply a polynomial calibration to an existing feed to create a virtual feed. This is the equation I’d like to apply: y = 0.0005x2 + 0.5466x + 2.7209 where y is the virtual feed and x is the existing feed. How can this be done in the virtual feed process list?

I think you need to write it in the form (0.0005x + 0.5466)x + 2.7209 = y
so

x [input]
× 0.0005
+ 0.5466
× x
+ 2.7209

= y

I have not tried it.
