Polynomial Equations and Inequalities

Enter a polynomial P and move the slider for b. This will show where y=b intersects your polynomial graph. You can then use this information to solve the equation P=b or inequalities P>b or P<b. To change the viewing window, hold the shift button and left-click to drag the graph or use the scroll wheel to zoom in/out. You can also adjust the axes by holding the shift button and left-click on the axis you want to change.
