Question 47891
If you put age on the x-axis and weight on the y-axis
the numbers on the x-axis might go from 0 to 85
and the numbers on the y-axis from 1 lb. to 200 lb.

Wouldn't the maximum weight lifted be when the man is
around age 35?  Wouln't the points follow a curve?
maybe the shape of a parabola?

Cheers,
Stan H.
