Hi,
Can someone have a look at the attachment and explain to me the bottom 3 lines of the table as I cant see where these figures come from.Also how can I draw a graph from these figure,by hand not excel etc.
Thanks....Mark
Hi manich44,
It looks to me like this is a table for your graph in your ealier post.
$\displaystyle f(h)=h^3+87.48h-305.73$
The first row of your table looks like arbitrary values for h.
The second row is the value of $\displaystyle h^3$
The third row is the value of $\displaystyle 87.48h$
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
$\displaystyle f(h)=h^3+87.48h-305.73$.
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.
