The Polynomial Calculator has functions for 1st, 2nd, 3rd, 4th and 5th degree polynomials. The user can enter the coefficients and the independent value (x) and see the resulting dependent value (y).
Plotting: These polynomial calculators have plotting enabled. You can enter the coefficients and then provide a range for x in the plot menu. The plot will show the y = f(x) graph based on the polynomial constants entered for the range.
