How do I find the mean of the line with the equation of y= 2x^2+4 from x=6 to x=12?

Answer 1

Before I would attempt to answer this I would want to be sure about the definition of "mean".

Probably this means (1/6)∫(2x² + 4)dx from 6 to 12.

In some situations it could also mean ∫x(2x² + 4))∫dx/(2x² + 4)dx...both integrals evaluated between 6 and 12
