Plotting function with a sequence of defined points
Answered
I am trying to plot the following function, as depicted in Figure f.png (attached):
f: y=50*Sum((abs(x_{i}x_{i1})),(i),(1),(12))+20*Sum((s_{i}),(i),(1),(12))
This always gives me an error ("Sorry, something went wrong. Please check your input"), but I do not know why.
Any pointers to my mistake(s) would be greatly appreciated!

The Sum command doesn't work on subscripts.
See https://wiki.geogebra.org/e...
Please post your file.
I think you must review the index of your expressions s_0 exist but x_0 not so one of from 1 to 12 is wrong
