Hi,
x={0,5,10,15,20,25};
f={-42,-37,-25,-6,15,36};
model=a+b*t+c*t^2;
param=FindFit[Transpose[{x,f}],model,{a,b,c},t]
Plot[Evaluate[model /. param],{t,0,25},Epilog->
Point /@ Transpose[{x,f}]]
Regards

| Hello,
|
|
|
| I hope someone could tell me where to look to or
if easy enough, to advise
| me on how to use Mathemetica for the type of
problem I have below. I
| already have worked it and have the lower
estimate to be -475 and the upper
| estimate to be -85. I was hoping to put
Mathematica to a practical use here
| and I really don't know how to do this. I have
typed the problem in
| exactly as shown in James Stewart's, Calculus
5th Edition.
|
|
|
| Here it is:
|
| A table of values of an increasing function f is
shown. Use the table to
| find lower and upper estimates for f(x) dx.
