Final answer:
A calculator can help you find the graph and roots of a polynomial by visualizing the curve and solving for the values that make the polynomial equal to zero.
Step-by-step explanation:
The calculator helps you find the graph and the roots of the given polynomial. By inputting the polynomial into the calculator, you can visualize the shape of the curve and how it changes with different constants. This can provide insights into the behavior of the polynomial and its solutions. Additionally, the calculator can help you solve for the roots of the polynomial, which are the values of the input variable that make the polynomial equal to zero.
