The best way to interpret polynomial regressions is to
A)take a derivative of Y with respect to the relevant X.
B)plot the estimated regression function and to calculate the estimated effect on Y associated with a change in X for one or more values of X.
C)look at the t-statistics for the relevant coefficients.
D)analyze the standard error of estimated effect.

Plotting the estimated regression function and calculating the estimated effect on Y associated with a change in X for one or more values of X is the best way to interpret polynomial regressions. This allows for a visual representation of the relationship between the variables and an understanding of how changes in X affect Y. The other options may provide useful information, but they do not give the full picture of the relationship between the variables.
