Graph Info
Polynomial graphing turns an algebraic expression into a visual curve so you can see roots, turning points, and end behavior more clearly.
Example: y = x^2 - 4 crosses the x-axis at -2 and 2.
Why is the graph smooth?
Polynomials are continuous and differentiable, so their graphs have no breaks.
Does the range matter?
Yes. A wider range shows more of the curve, while a tighter range shows more detail.
Can I graph decimals?
Yes. Any finite real coefficients are accepted.
What if the coefficients are invalid?
The graph will not render until valid coefficients and a valid range are entered.
