How do you graph #f(x)=5x^3-7x^2-49x+51# on a calculator, use the graph to guess the possible linear factors of f(x). then completely factor f(x) with the aid of synthetic division?

All graphing is done by setting up the equation and generating sets of (x,y) points to plot.
The roots may best observed from the plot. The accuracy just depends on the resolution of your graph. Factoring is a separate operation from graphing.
