Hi manich44,

It looks to me like this is a table for your graph in your ealier post.

The first row of your table looks like arbitrary values for h.

The second row is the value of

The third row is the value of

The fourth row is the value of the constant 305.73.

The fifth row is the value of f(h) when you substitute values from row one into

.

To graph manually, plot the domain coordinate from the first row along with its corresponding range coordinate from the fifth row.

You'll have to use a graphing calculator or the Cubic Formula to find the zero which I already told you in the other post.
