I always doubt the usefulness of the excel equation myself.

Anyway, the 2E-09 is 0.000000002, and 2E-7 is 0.0000002, and the 3E-05 is the scientific notation of long decimal number. Basically, it's 0.00003.

If X is in column A, and Y is in column B starting in row 2, you can put the following formula in B2 to calculate the Y based on X in A2.

=(0.000000002*A2^4)-(0.0000002*A2^3)+(0.00003*A2^2)+(0.0002*A2)+0.0012
