Hey, I have some data points:

 

I than entered:

X := Data[() .. (), 1];
Y := Data[() .. (), 2];
f := a+b*x^c+d*x^e;
Statistics:-NonlinearFit(f, X, Y, x);
 and when I entered Statistics:-NonlinearFit(f, X, Y, x);, It wouldn't output anything.

Hi, I am trying to plot these two curves:

I tried:


with(plots);  A := Array(1..2)  A[1] :=plot (0.199563349672261+0.0178636902277546 x^1.14406289706794-0.0182070811144750 x^(1.13867380551454),x=50..2050,  color=red);  A[2]  := plot(0.298910542599302+0.0117459591500434 x^1.00390277106937-0.0137065176395662 x^0.970667551759677, x = 50..2050, color = blue);  display (A);

and I got:

Error, (in plot) unexpected option: .298910542599302+0.117459591500434e-1*x^1.00390277106937-0.137065176395662e-1*x^.970667551759677

so I tried

so I am not sure how I would graph these two functions...

Hello, i am working on creating a smooth curve from my data points: [0.2e-1, .158], [0.2e-1, .159], [0.3e-1, .161], [0.3e-1, .164], [0.3e-1, .166], [0.4e-1, .169], [0.6e-1, .173], [0.8e-1, .178], [.1, .185], [.11, .187], [.14, .193], [.19, .2], [.28, .21], [.38, .223], [.44, .233], [.58, .244], [.82, .256], [1.4, .278], [1.71, .281], [1.78, .282], [1.78, .282], [1.81, .282]

however, I am not sure how to to create the smooth curve formula for said data points. I tried using polycurve, but it didn't spit out any equations.
