I am trying to plot y:=x^2+x-12 as a curve and as a series of point. It is just not working. Suggestions, please.

restart

f := proc (x) options operator, arrow; x^2+x-12 end proc

n := 10

h := 5``

printf("\n i x f (dec.form) f (sci. notat.)\n"); printf(" ---------------------------------------------------\n"); for i from 0 to n do X[i] := i*h; Y[i] := f(X[i]); printf(" %5d %9.4f %13.9f %17.10e\n", i, X[i], Y[i], Y[i]) end do
