I want to plot the cubic equation f(x) == x^3 - 16x^2 + 3x + 1 == 0. I had:
f==x^3-16 x^2+3 x+1 ==== 0
but I was unable to get the plot. The error message says
Plot::plnr: f is not a machine-size real number at x == -0.999999.
Plot::plnr: f is not a machine-size real number at x == -0.148093.
Plot::plnr: f is not a machine-size real number at x == 0.780985.
General::stop: Further output of Plot::plnr
will be suppressed during this calculation.
How do I get around this problem?
